BUG: Spotify Connect - Using Radio function on controlling device causes disconnect

[MrWorf]

Whenever I try to use the radio function on a device (A) which is controlling the playback of another device (B), my playback device (B) will disconnect from Spotify Connect and I have to force close and start it again on the playback device (B) to see it on the controlling device (A). I have so far never been able to use Radio over Spotify Connect.
