Re: [csswg-drafts] [css-contain][css-sizing] Behavior of slightly offscreen content having `content-visibility:auto` and `contain-intrinsic-size` when UA margin around the viewport is 0 (#8407)

I kind of think that used value is actually a little easier to deal with. I'm not sure what's meant to happen if there's a developer style that says something like `content-visibility: auto; contain-intrinsic-size: none !important`. I assume the language that says c-v auto forces c-i-s auto supersedes any other style interaction, which is why at used value time we can just check either one of those.

But computed style time would also work. In Blink, we just have to be careful about the ordering: first we need to adjust to have c-i-s auto and then do all the required work to deal with c-i-s auto

I guess I'm saying I have no strong preference, so if computed is easier for Gecko, then we can go with that
