How do you avoid cycles?

:visible { display: none }

And BTW, `:first-child:visible` would match the first child *if* it's visible, instead of the first visible child. That would be `:nth-child(1 of :visible)`.

I think it would be easier to cover this usecase with a `:metadata` pseudo-class, matching [metadata content](https://html.spec.whatwg.org/#metadata-content-2): `base`, `link`, `meta`, `noscript`, `script`, `style`, `template`, `title`. But I'm not convinced this is worth it.
