"play radio" button does odd things
Procedure to reproduce:
- go to https://audio.gafamfree.party/library/radios (for example)
- pick up a radio and press "play radio"
- observe that the button text switches to "stop radio", while the button style stays the same
- click anywhere on a blank area
- observe that the button style changes
Second issue: (solution : "enable/disable" rather than "play/stop")
- press "stop radio"
- observe the button state changes, but music keeps playing
- expected behavior would be that the playback stops when the radio is stopped
- that RSS icon
- radio may skip several tracks one after another
- radio would stop after too much failure #1709 (closed)
