// This is temporary: A bug is being fixed that will make subscribe
// consistently call onChildrenLoaded initially, no matter if it is replacing an existing
// subscriber or not. Currently this only happens if the mediaID has no previous
// subscriber or if the media content changes on the service side, so we need to
// unsubscribe first.
