Re: [csswg-drafts] [selectors-4] Introduce `:popover` pseudo class (#8637)

> One thing I suggested in the [OpenUI discussion](https://www.w3.org/2023/03/23-openui-minutes.html#t05) is that `:open` and `:closed` could be for anything where the open/closed state is related to the _element_ semantics, but that things like popover and fullscreen (which can be applied to any element) should have separate pseudo-classes to distinguish them and avoid this problem of unexpected intersections.

This also seems like a reasonable suggestion. @jh3y do you know of any popover use cases that would be harmed by not having access to a `:closed` pseudo class? It seems like `:not(:popover)` would generally work instead, but just checking.
