Summary CSSStyleSheets don't invalidate properly inside ShadowDOM

Reported 2024-02-19 09:02:20 PST
See https://github.com/web-platform-tests/wpt/pull/44651/files#diff-777de6c8f8778f17b038c684801ce25570c823ee8f38daec836ed9a1cb255ad1R36-R48 for a repro. Creating a CSSStyleSheet and adopting it, then setting inner properties on the sheet, does not always perform invalidation.

Created attachment 469961 [details] Interactive test case I’ve had this in my backlog to file for about a month (sorry). I made an interactive test case for it which allows you to switch between the document and the shadowroot as well as between updating styles with `CSSStyleDeclaration` and `StylePropertyMap`.

This is really inconvenient. It would be great to resolve this unreliable behaviour.
