OK, I noticed today that I had a bunch of MPRIS notifications hanging around even though no applications using WebKit were running, and finally checked this out. I noticed three different hung web processes, alive after the UI process exited. I killed them using core signals and examined the backtrace using flatpak-coredumpctl. Two of them were the same bug, which I'll report in bug #247057. The other one was a different bug; I didn't properly save that one, and will have to report it separately next time I see it.

So let's handle the web process hangs elsewhere, and save the rest of this bug report for dealing with MPRIS. I don't have time to investigate and fix things properly right now, but I could post a hack patch to just sabotage MediaSessionGLib and avoid the immediate problem. Carlos Garcia doesn't generally like it when I do that, though. :)
