Steps to reproduce:

Conditions: Audiobook, and another audio app (app B) are both open.

1. play audiobook
2. toggle to different open audio (app B)
3. play in app B: audiobook should auto-pause (via audio-interrupt)
4. go back to audiobook (app B should auto-pause) and audiobook is paused.
5. tap play
6. tap pause in audiobook
7. go to app B and play
8. toggle back to audiobook app (while app B is still playing

Audiobook should stay paused, but it auto-plays.

This bug seems to only happen when an initial pause is caused in the Audiobook app by audio-interruption from another app.

Whereas, if you first tap pause in audiobook (app A) without  app B already open, then you open app B and play, when you return to the audiobook app it will still remain paused as expected.
