[csswg-drafts] [css-anchor-position] Let more pseudo-elements have implicit anchor elements (#11792)

tabatkins has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-anchor-position] Let more pseudo-elements have implicit anchor elements ==
In #10494 we're discussing having `::scroll-marker-group` use its originating element as its "implicit anchor element", so as long as you don't override anything you can just immediately use `position: absolute; position-area: bottom center;` or similar to position the group.

@flackr brought up that it might make sense to extend this to more tree-abiding pseudos, and make them *all* use their originating element as their implicit anchor element. For example, `::before` would default to positioning relative to the element it's generated for.

This sounds like a reasonable idea? It's technically a behavior change, but only with regards to content that is setting the anchor-pos properties *on* pseudo-elements *without* setting a `position-anchor` value. That seems vanishingly unlikely at this point in the feature's life.
