[Messages vs Music Control] vibration pattern doesn't stop

### Affected hardware version

Bangle 2

### Your firmware version

2v24

### The bug

With active (loaded) music control app, a notification alarm doesn't stop after the configured timeout, instead the pattern is repeated until the music app is closed by pressing hw-button two seconds.
Short Pressing the button only changes play/pause state

- It doesn't matter if music is playing or not when the message is received.
- It doesn't matter if the music control app is started automatically or by hand.
- It doesn't matter if "Auto-Open Music" is dis- or enabled.
- Configuration of Messages UI seems to make no difference.

MessagesUI is configured as follows:
- Vibrate ::
- Vibrate for calls ::
- Repeat 5s
- Repeat for calls 5s
- Vibrate timer Off
- Unread timer 10s
- Min Font Small (default)
- Auto-Open Music [ ]/[v] (both tested)
- Unlock Watch [v]
- Flash Icon [ ]
- Quiet Mode disables auto.open [ ]
- Disable auto-open [ ]
- Widget Messages 3 (default)
- Icon color mode color (default)
- Car driver pos lef (default)

No source file or test is named. Start by reproducing the issue on a Bangle 2 with firmware 2v24 and the listed Messages UI and Music Controls versions, then inspect how their notification vibration and music-control state interact. Done means the configured notification pattern stops at its timeout while the music controls remain usable.
