adapt-contrib-media issue - mp3 audio pauses immediately without clicking pause button.

Your environment

Framework version: 5.15.0
Component version: 5.2.1
Browser: Firefox 89.0.2 (64-bit)
PC Windows 10

Steps to reproduce

Set component to play mp3 audio and include "_pauseWhenOffScreen": true in options.
Toggle between true & false for that option. Problem disappears when set to false.

Expected behaviour

Audio file should continue playing until component is off screen.

Actual behaviour

Audio plays for a split second then pauses automatically, while the component is still on screen. Essentially, the file doesn't play.
