Just retested and could not reproduce this on my device on this site. QA could we verify this is working properly on your devices? Thanks!

Ah I understand now, the volume bar works, it's just a visual thing. I can also reproduce in Fennec.

The Media team commented on the bugzilla issue at https://bugzilla.mozilla.org/show_bug.cgi?id=1629972#c1 saying that they believe this to be a Fenix problem, not a Gecko one. I see here that it is also reproducible in Fennec. I've requested more information from the Media team, but someone from Fenix might want to weigh in here somewhere.
