- * 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.
