Galaxy S22 ultra running android 14

Devices that do not reproduce the issue

No response

Reproducible in the demo app?

Yes

Reproduction steps

1. Modify PlaybackService's onTaskRemoved so that it will terminate even if the music is running (Simply calling pauseAllPlayersAndStopSelf() is mentioned in the documentation, so I used just that)
   
2. Optionally add a static integer variable that gets printed and incremented at the start of the app to help with observing the bug
   
   
3. Launch the app and start playing music
4. Swipe the app away from recents while the music is playing
5. Launch the app again

Expected result

The static integer value gets reset and prints the same value on both launches

Actual result

The static integer retains it's incremented value and prints different values
