  By using this `CustomElement` interface instead of `HTMLElement`, we avoid

  TypeScript. This is particularly useful since different versions of
  TypeScript may have different DOM API typings (e.g. TS 3.0.3 and TS 3.1.1).
  The required `isConnected` property is included to avoid the following

      Type 'HTMLElement' has no properties in common with type 'CustomElement'.
