This is never called with false, can't the
stateChanged(WebRemotePlaybackState::Connected) call be used to resolve the
promise?

Done. I'll need it later when I plumb the dialog closures back to
HTMLMediaElement but I will add it then :)

         remotePlaybackClient()->stateChanged(WebRemotePlaybackState::Connected);
+    }
 }
