There is no such concept of isolation boundary in CSS right now, right?

I don't think they will be trivial to spec, and they will be even less 
trivial to implement.

And that wouldn't address the other issues with animations/transitions, 
or with other future things the CSSWG adds while thinking that there is 
an invariant that display:none things don't affect CSS rendering.

At some point you may want to step back and think about how much 
complexity you really want to add to support what's fundamentally an 
edge case and whether a simpler solution in spec terms might be better.
