Re: [csswg-drafts] [css-conditional-5][css-nesting-1] Feature detection for nesting (#8399)

For `@supports selector(&) {}` to be useful it is also critical that browsers ship support for the nesting selector at the root at the same time as actual nesting : https://github.com/w3c/csswg-drafts/issues/5745#issuecomment-1302487789

I've created a pull request with a basic WPT test : https://github.com/web-platform-tests/wpt/pull/38373

Currently Chrome and Safari TP do not support `&` at the root.
If they were to ship today there would be no way to detect support for `&` at the root in the future.
