If you play an internet radio stream and want to switch to another one and click on it you expect it to play but instead the previous radiostream only stops and you have to click on the wanted stream again to start it playing.
This only happens with Internet Radio Streams, not with DVB-S/DVB-C Radio Streams. It also happens with internet radio plugins like RadioTime.
