Quran.com stops playing in the background unless Vanadium has Unrestricted battery set.

Steps to reproduce:

1. Open Quran.com
2. Choose any Surah.
3. Press on the three bottom dots.
4. Press on "Manage repeat settings".
5. Select "Full Surah" at the top.
6. Increase "Play Range" to "infinite".
7. Decrease "Repeat each verse" to "1".
8. Decrease "Delay between verse" to "0".
9. Press "Start Playing"
10. Lock Phone.
11. Observe that playback stops after several seconds.

Not sure if this is a website issue or a Vanadium issue. It seems that between each verse, the website completely pauses playback and then starts it up for the next verse as can be observed by looking at the media player while a Surah is playing. However, this used to work with Vanadium having battery set to optimised but it stopped working about a year ago.
