-// MediaPermission implementation which dispatches queries/requests to Mojo
-// PermissionService. It relies on its base class MediaPermissionDispatcher to
-// manage pending callbacks. Non-UI threads could create
-// MediaPermissionDispatcherProxy by calling CreateProxy such that calls will be
-// executed on the UI thread which is where this object lives.
