/**
|
||
|
|
* lit-html patch to support browsers without native web components.
|
||
|
|
*
|
||
|
|
* This module should be used in addition to loading the web components
|
||
|
|
* polyfills via @webcomponents/webcomponentjs. When using those polyfills
|
||
|
|
* support for polyfilled Shadow DOM is automatic via the ShadyDOM polyfill.
|
||
|
|
* Scoping classes are added to DOM nodes to facilitate CSS scoping that
|
||
|
|
* simulates the style scoping Shadow DOM provides. ShadyDOM does this scoping
|
||
|
|
* to all elements added to the DOM. This module provides an important
|
||
|
|
* optimization for this process by pre-scoping lit-html template
|
||
|
|
* DOM. This means ShadyDOM does not have to scope each instance of the
|
||
|
|
* template DOM. Instead, each template is scoped only once.
|
||
|
|
*
|
||
|
|
* Creating scoped CSS is not covered by this module. It is, however, integrated
|
||
|
|
* into the lit-element and @lit/reactive-element packages. See the ShadyCSS docs
|
||
|
|
* for how to apply scoping to CSS:
|
||
|
|
* https://github.com/webcomponents/polyfills/tree/master/packages/shadycss#usage.
