Re: [csswg-drafts] [css-values] attr() and part() / slotted() / element backed pseudo-elements behave inconsistently. (#12721) from Tab Atkins Jr. via GitHub on 2026-02-11 (public-css-archive@w3.org from February 2026)

So, clarification still needed here: are we intending to introduce a tree-scoping mechanism for the styles, then?

Because otherwise, the behavior of author styles inside the pseudo will change behavior based on whether the element is exposed as a part or not.
