I would expect the entire web page ought to be destroyed? But perhaps a leak keeps the HTMLMediaElement alive?

This is unrelated to process suspension. Currently there is no process suspension (bug #262794), but even if that was fixed, it's just SIGSTOP/SIGCONT, so suspending the process would only delay the bug until the process is restored from page cache.

Anyway, I'll try to revert for now. We'll just have to try again.
