 // It is not a common implementation of PlatformEventDispatcher in the sense
 // that it doesn't actually dispatch events but simply start/stop listening. The
 // reason being that screen orientation events are always sent to the WebFrame's
 // but some platforms require to poll to have an accurate reporting. When
 // ScreenOrientationDispatcher is listening, that means that the platform should
 // be polling if required.
