Thanks, I hadn't seen this before. I assume this would be queryable with `CSS.supports('at-rule(@media; some-feature)')`!? In a contrived example where `(some-feature: value1 | value2)`, but where only `value2` would be supported, could you somehow query this (with CSS or JS)? I guess more concretely I'm actually asking if `CSS.supports('at-rule(@media; (prefers-color-scheme: dark)')` would work, or only `CSS.supports('at-rule(@media; prefers-color-scheme')`. The way I read it, both should work?!
