I also reproduced this when an app is maximized then peeked to desktop (with Super+D) and then locked the screen.

Note: I observed that when an app is maximized, if the normal wallpaper (not the lock screen but the desktop) is also live, it stops until the desktop can be seen (by peeking at desktop or minimizing etc.). I don't know the inner mechanics but I assume there is optimization going on with stopping the playback when the desktop is not seen. This might also be affecting the lock screen playback mechanism
