Audio Player resumes sound if closed.

[ExDrill]

Summary
The recently added audio player has one major bug that I've observed. Closing a tab when audio is playing will keep the audio on. Going back on the tab and playing again doesn't fix it, nor does it start off as "playing".

To Reproduce
Steps to reproduce the behavior:

1. Open a new audio tab in bridge.
2. Play the audio and close the tab.
3. Observe results

Observed behavior
The audio keeps playing
Expected behavior
The audio shouldn't be playing when the tab is closed.
