Re: [csswg-drafts] [css-nesting-1] Clearer definition of “nest-containing” (#7972)

Option 2 seems fine to me; I don't honestly think people will be writing  `:is(:unknown(&), .bar)` too much in the first place (surely, `:is(:unknown(&), & .bar)` would be a more common case?). We have to give up something, and between handling forward-compatibility and distinguishing between `&` inside and and outside of parens, the latter seems more broadly useful to me. (“Just don't nest” is limiting the standard unneccessarily, I'd feel? As long as we've said nesting is something fundamentally different from `@scope` and more like a grouping handling similar to a macro, we should probably accept these cases as equally valid.)
