Re: [csswg-drafts] [selectors] Let :is() have better error-recovery behavior than normal Selectors (#3264)

Just verifying as I write the spec - in <https://github.com/w3c/csswg-drafts/issues/3264#issuecomment-441148706> @ewilligers suggested that we handle "single selector, which is invalid" differently from the rest of the cases, since that has legacy implications, but it looks like we're no longer doing that?

That is, `:is(:unknown)` is valid but matches nothing, just like `:is()` and `:is(:unknown1, :unknown2)`?
