Assuming that the use case here is "display an alert, confirmation, or
prompt, but make it possible to do so while continuing to run background
animations and the like", it seems like a better solution would be to
introduce a <dialog> element so that authors can design inline dialog
boxes that do whatever they want, including being able to style them, etc.
This would solve multiple problems at once.
I've been considering such a feature for some time. Some JS libraries
already support things a bit like this; part of designing an element and
associated API to do this built-in to the platform will be researching how
those APIs work today. If anyone is interested in helping out with this,
please let me know, or just start putting data on a wiki page.

I haven't changed the spec with regard to this.

Not sure how this would work.

Yeah, I never got around to speccing that. I've added it. It does nothing.

That's somewhat unrelated (though equally useless these days).
