Steps to reproduce the issue:

1. On iPhone with iOS 12.1 or above (I used iPhone X iOS 13).
2. Go on the below provided URL in Safari and click play.
3. Wait for a few second, then swipe at the bottom of the screen to exit the browser, or just swipe the home screen or a different app.
4. Wait for a few second, then swipe back to Safari.
5. When you come back you will see the playback is stuck and the Play and pause functionalities are not working.

I was able to reproduce this on a regular m3u8 stream:

Please note, that I was able to achieve a workaround by "nudging" the current time of the video Element just a bit (0.1).

The issue reproduces on the following players as well:
 
JWPlayer,
Dailymotion,
Video JS,
Kaltura

FYI, No error codes are prompted during this issue, therefore I do not think that this is the same error as 195452.
