   * Helper property with theme attribute value facilitating propagation

   * Enables the component implementation to propagate the `theme`
   * attribute value to the sub-components in Shadow DOM by binding
   * the sub-component's "theme" attribute to the `theme` property of
   * the host.
   *
   * **NOTE:** Extending the mixin only provides the property for binding,
   * and does not make the propagation alone.
