- * `dom-repeat` accepts an `items` property, and one instance of the template
- * is stamped for each item into the DOM at the location of the `dom-repeat`
- * element. The `item` property will be set on each instance's binding
- * scope, thus templates should bind to sub-properties of `item`.
- *
- * Example:
- *
- * ```html
- * <dom-module id="employee-list">
- *
- * <template>
- *
- * <div> Employee list: </div>
- * <template is="dom-repeat" items="{{employees}}">

- * ...
- * ];
- * }
- * });
- * < /script>
- *
- * </dom-module>
- * ```
- *
- * Notifications for changes to items sub-properties will be forwarded to template
- * instances, which will update via the normal structured data notification system.
- *
- * Mutations to the `items` array itself should me made using the Array
- * mutation API's on `Polymer.Base` (`push`, `pop`, `splice`, `shift`,
- * `unshift`), and template instances will be kept in sync with the data in the
- * array.
- *
- * Events caught by event handlers within the `dom-repeat` template will be
- * decorated with a `model` property, which represents the binding scope for
- * each template instance. The model is an instance of Polymer.Base, and should
- * be used to manipulate data on the instance, for example
- * `event.model.set('item.checked', true);`.
- *
- * Alternatively, the model for a template instance for an element stamped by
- * a `dom-repeat` can be obtained using the `modelForElement` API on the
- * `dom-repeat` that stamped it, for example
- * `this.$.domRepeat.modelForElement(event.target).set('item.checked', true);`.
- * This may be useful for manipulating instance data of event targets obtained
- * by event handlers on parents of the `dom-repeat` (event delegation).
- *
- * A view-specific filter/sort may be applied to each `dom-repeat` by supplying a
- * `filter` and/or `sort` property. This may be a string that names a function on
- * the host, or a function may be assigned to the property directly. The functions
- * should implemented following the standard `Array` filter/sort API.
- *
- * In order to re-run the filter or sort functions based on changes to sub-fields
- * of `items`, the `observe` property may be set as a space-separated list of
- * `item` sub-fields that should cause a re-filter/sort when modified. If
- * the filter or sort function depends on properties not contained in `items`,
- * the user should observe changes to those properties and call `render` to update
- * the view based on the dependency change.
- *
- * For example, for an `dom-repeat` with a filter of the following:
- *
- * ```js
- * isEngineer: function(item) {
- * return item.type == 'engineer' || item.manager.type == 'engineer';
- * }
- * ```
- *
- * Then the `observe` property should be configured as follows:
- *
- * ```html
- * <template is="dom-repeat" items="{{employees}}"
- * filter="isEngineer" observe="type manager.type">
- * ```

- * Generates a class that extends `Polymer.LegacyElement` based on the

- * (`properties`, `observers`, `listeners`, `behaviors`, `is`) are used
- * for Polymer's meta-programming systems, and any functions are copied
- * to the generated class.
- *
- * Valid "metadata" values are as follows:
- *
- * `is`: String providing the tag name to register the element under. In
- * addition, if a `dom-module` with the same id exists, the first template
- * in that `dom-module` will be stamped into the shadow root of this element,
- * with support for declarative event listeners (`on-...`), Polymer data
- * bindings (`[[...]]` and `{{...}}`), and id-based node finding into
- * `this.$`.
- *
- * `properties`: Object describing property-related metadata used by Polymer
- * features (key: property names, value: object containing property metadata).
- * Valid keys in per-property metadata include:
- * - `type` (String|Number|Object|Array|...): Used by
- * `attributeChangedCallback` to determine how string-based attributes
- * are deserialized to JavaScript property values.
- * - `notify` (boolean): Causes a change in the property to fire a
- * non-bubbling event called `<property>-changed`. Elements that have
- * enabled two-way binding to the property use this event to observe changes.
- * - `readOnly` (boolean): Creates a getter for the property, but no setter.
- * To set a read-only property, use the private setter method
- * `_setProperty(property, value)`.
- * - `observer` (string): Observer method name that will be called when
- * the property changes. The arguments of the method are
- * `(value, previousValue)`.
- * - `computed` (string): String describing method and dependent properties
- * for computing the value of this property (e.g. `'computeFoo(bar, zot)'`).
- * Computed properties are read-only by default and can only be changed
- * via the return value of the computing method.
- *
- * `observers`: Array of strings describing multi-property observer methods
- * and their dependent properties (e.g. `'observeABC(a, b, c)'`).
- *
- * `listeners`: Object describing event listeners to be added to each
- * instance of this element (key: event name, value: method name).
- *
- * `behaviors`: Array of additional `info` objects containing metadata
- * and callbacks in the same format as the `info` object here which are
- * merged into this element.
- *
- * `hostAttributes`: Object listing attributes to be applied to the host
- * once created (key: attribute name, value: attribute value). Values
- * are serialized based on the type of the value. Host attributes should
- * generally be limited to attributes such as `tabIndex` and `aria-...`.
- * Attributes in `hostAttributes` are only applied if a user-supplied
- * attribute is not already present (attributes in markup override
- * `hostAttributes`).
- *
- * In addition, the following Polymer-specific callbacks may be provided:
- * - `registered`: called after first instance of this element,
- * - `created`: called during `constructor`
- * - `attached`: called during `connectedCallback`
- * - `detached`: called during `disconnectedCallback`
- * - `ready`: called before first `attached`, after all properties of
- * this element have been propagated to its template and all observers
- * have run
- *
- * @param {Object} info Object containing Polymer metadata and functions
- * to become class methods.
- * @return {Polymer.LegacyElement} Generated class

- * The `Polymer.Templatizer` behavior adds methods to generate instances of
- * templates that are each managed by an anonymous `Polymer.PropertyEffects`
- * instance where data-bindings in the stamped template content are bound to
- * accessors on itself.
- *
- * This behavior is provided in Polymer 2.x as a hybrid-element convenience
- * only. For non-hybrid usage, the `Polymer.Templatize` library
- * should be used instead.
- *
- * Example:
- *
- * // Get a template from somewhere, e.g. light DOM
- * let template = this.querySelector('template');
- * // Prepare the template
- * this.templatize(template);
- * // Instance the template with an initial data model
- * let instance = this.stamp({myProp: 'initial'});
- * // Insert the instance's DOM somewhere, e.g. light DOM
- * Polymer.dom(this).appendChild(instance.root);
- * // Changing a property on the instance will propagate to bindings
- * // in the template
- * instance.myProp = 'new value';
- *
- * Users of `Templatizer` may need to implement the following abstract
- * API's to determine how properties and paths from the host should be
- * forwarded into to instances:
- *
- * _forwardHostPropV2: function(prop, value)
- *
- * Likewise, users may implement these additional abstract API's to determine
- * how instance-specific properties that change on the instance should be
- * forwarded out to the host, if necessary.
- *
- * _notifyInstancePropV2: function(inst, prop, value)
- *
- * In order to determine which properties are instance-specific and require
- * custom notification via `_notifyInstanceProp`, define an `_instanceProps`
- * object containing keys for each instance prop, for example:
- *
- * _instanceProps: {
- * item: true,
- * index: true
- * }
- *
- * Any properties used in the template that are not defined in _instanceProp
- * will be forwarded out to the Templatize `owner` automatically.
- *
- * Users may also implement the following abstract function to show or
- * hide any DOM generated using `stamp`:
- *
- * _showHideChildren: function(shouldHide)
- *
- * Note that some callbacks are suffixed with `V2` in the Polymer 2.x behavior
- * as the implementations will need to differ from the callbacks required

- * The getter may return an `HTMLTemplateElement` or a string, which will
- * automatically be parsed into a template.
- *
- * - `static get properties()`: Should return an object describing
- * property-related metadata used by Polymer features (key: property name
- * value: object containing property metadata). Valid keys in per-property
- * metadata include:
- * - `type` (String|Number|Object|Array|...): Used by
- * `attributeChangedCallback` to determine how string-based attributes
- * are deserialized to JavaScript property values.
- * - `notify` (boolean): Causes a change in the property to fire a
- * non-bubbling event called `<property>-changed`. Elements that have
- * enabled two-way binding to the property use this event to observe changes.
- * - `readOnly` (boolean): Creates a getter for the property, but no setter.
- * To set a read-only property, use the private setter method
- * `_setProperty(property, value)`.
- * - `observer` (string): Observer method name that will be called when
- * the property changes. The arguments of the method are
- * `(value, previousValue)`.
- * - `computed` (string): String describing method and dependent properties
- * for computing the value of this property (e.g. `'computeFoo(bar, zot)'`).
- * Computed properties are read-only by default and can only be changed
- * via the return value of the computing method.
- *
- * - `static get observers()`: Array of strings describing multi-property
- * observer methods and their dependent properties (e.g.
- * `'observeABC(a, b, c)'`).
- *
- * The base class provides default implementations for the following standard
- * custom element lifecycle callbacks; users may override these, but should

- * - `disconnectedCallback`: Run each time the element is disconnected from

- *
- * The info object should may contain property metadata as follows:
- *
- * * `type`: {function} type to which an attribute matching the property
- * is deserialized. Note the property is camel-cased from a dash-cased
- * attribute. For example, 'foo-bar' attribute is dersialized to a
- * property named 'fooBar'.
- *
- * * `readOnly`: {boolean} creates a readOnly property and
- * makes a private setter for the private of the form '_setFoo' for a
- * property 'foo',
- *
- * * `computed`: {string} creates a computed property. A computed property
- * also automatically is set to `readOnly: true`. The value is calculated
- * by running a method and arguments parsed from the given string. For
- * example 'compute(foo)' will compute a given property when the
- * 'foo' property changes by executing the 'compute' method. This method
- * must return the computed value.
- *
- * * `reflectToAttriute`: {boolean} If true, the property value is reflected
- * to an attribute of the same name. Note, the attribute is dash-cased
- * so a property named 'fooBar' is reflected as 'foo-bar'.
- *
- * * `notify`: {boolean} sends a non-bubbling notification event when
- * the property changes. For example, a property named 'foo' sends an
- * event named 'foo-changed' with `event.detail` set to the value of
- * the property.
- *
- * * observer: {string} name of a method that runs when the property
- * changes. The arguments of the method are (value, previousValue).
- *
- * Note: Users may want control over modifying property
- * effects via subclassing. For example, a user might want to make a
- * reflectToAttribute property not do so in a subclass. We've chosen to
- * disable this because it leads to additional complication.
- * For example, a readOnly effect generates a special setter. If a subclass
- * disables the effect, the setter would fail unexpectedly.
- * Based on feedback, we may want to try to make effects more malleable
- * and/or provide an advanced api for manipulating them.

- * Element class mixin to add the optional ability to skip strict

- * "dirty") by setting a `mutable-data` attribute on an element instance.
- *
- * By default, `Polymer.PropertyEffects` performs strict dirty checking on
- * objects, which means that any deep modifications to an object or array will
- * not be propagated unless "immutable" data patterns are used (i.e. all object
- * references from the root to the mutation were changed).
- *
- * Polymer also provides a proprietary data mutation and path notification API
- * (e.g. `notifyPath`, `set`, and array mutation API's) that allow efficient
- * mutation and notification of deep changes in an object graph to all elements
- * bound to the same object graph.
- *
- * In cases where neither immutable patterns nor the data mutation API can be
- * used, applying this mixin will allow Polymer to skip dirty checking for
- * objects and arrays (always consider them to be "dirty"). This allows a
- * user to make a deep modification to a bound object graph, and then either
- * simply re-set the object (e.g. `this.items = this.items`) or call `notifyPath`
- * (e.g. `this.notifyPath('items')`) to update the tree. Note that all
- * elements that wish to be updated based on deep mutations must apply this
- * mixin or otherwise skip strict dirty checking for objects/arrays.
- *
- * While this mixin adds the ability to forgo Object/Array dirty checking,
- * the `mutableData` flag defaults to false and must be set on the instance.
- *
- * Note, the performance characteristics of propagating large object graphs
- * will be worse by relying on `mutableData: true` as opposed to using
- * strict dirty checking with immutable patterns or Polymer's path notification
- * API.

- * Returns an anonymous `Polymer.PropertyEffects` class bound to the
- * `<template>` provided. Instancing the class will result in the
- * template being stamped into document fragment stored as the instance's
- * `root` property, after which it can be appended to the DOM.
- *
- * Templates may utilize all Polymer data-binding features as well as
- * declarative event listeners. Event listeners and inline computing
- * functions in the template will be called on the host of the template.
- *
- * The constructor returned takes a single argument dictionary of initial
- * property values to propagate into template bindings. Additionally
- * host properties can be forwarded in, and instance properties can be
- * notified out by providing optional callbacks in the `options` dictionary.
- *
- * Valid configuration in `options` are as follows:
- *
- * - `forwardHostProp(property, value)`: Called when a property referenced
- * in the template changed on the template's host. As this library does
- * not retain references to templates instanced by the user, it is the
- * templatize owner's responsibility to forward host property changes into
- * user-stamped instances. The `instance.forwardHostProp(property, value)`
- * method on the generated class should be called to forward host
- * properties into the template to prevent unnecessary property-changed
- * notifications. Any properties referenced in the template that are not
- * defined in `instanceProps` will be notified up to the template's host
- * automatically.
- * - `instanceProps`: Dictionary of property names that will be added
- * to the instance by the templatize owner. These properties shadow any
- * host properties, and changes within the template to these properties
- * will result in `notifyInstanceProp` being called.
- * - `mutableData`: When `true`, the generated class will skip strict
- * dirty-checking for objects and arrays (always consider them to be
- * "dirty").
- * - `notifyInstanceProp(instance, property, value)`: Called when
- * an instance property changes. Users may choose to call `notifyPath`
- * on e.g. the owner to notify the change.
- * - `parentModel`: When `true`, events handled by declarative event listeners
- * (`on-event="handler"`) will be decorated with a `model` property pointing
- * to the template instance that stamped it. It will also be returned
- * from `instance.parentModel` in cases where template instance nesting
- * causes an inner model to shadow an outer model.
- *
- * Note that the class returned from `templatize` is generated only once
- * for a given `<template>` using `options` from the first call for that
- * template, and the cached class is returned for all subsequent calls to
- * `templatize` for that template. As such, `options` callbacks should not
- * close over owner-specific properties since only the first `options` is
- * used; rather, callbacks are called bound to the `owner`, and so context
- * needed from the callbacks (such as references to `instances` stamped)
- * should be stored on the `owner` such that they can be retrieved via `this`.

This is accomplished by changing the property set to this:\n *\n * --foo_-_border: 2px solid red;\n * --foo_-_color: initial;\n * --foo_-_background: initial;\n *\n * This works but introduces one new issue.\n * Consider this setup at the point where the `@apply` is used:\n *\n * background: orange;\n * `@apply` --foo;\n *\n * In this case the background will be unset (initial) rather than the desired\n * `orange`. We address this by altering the property set to use a fallback\n * value like this:\n *\n * color: var(--foo_-_color);\n * background: var(--foo_-_background, orange);\n * border: var(--foo_-_border);\n *\n * Note that the default is retained in the property set and the `background` is\n * the desired `orange`.
