"Radio does not support pause" when switching to other source

When you listen to the radio and want to switch to default music app (Spotify in my case), there's "Radio does not support pause" error. There's no such message when swithing to Bluetooth music or system player

Steps to reproduce:

1. Open Radio app
2. Go to the main screen and open Music Widget
3. Switch to the last music source (default music app)

Expected result:
Music switches to the new source

Current result:
Radio does not support pause is displayed
