Re: [csswg-drafts] [css-shadow-parts] Should `::part():lang()` and `::part():dir()` be valid? (#9795)

I guess the question is "do we consider `:dir()` and `:lang()` to "reveal tree structure"? I think you could say they do... If so, they should never match, probably.

Given https://github.com/whatwg/html/pull/9880#issuecomment-1892568094 I'd much rather make them invalid for now and make a decision once all those HTML issues about how language and directionality work in the shadow DOM are settled.
