As far as detecting support, one approach we could take is adding a new [named feature](https://drafts.csswg.org/css-conditional-5/#support-definition-named-features) to the `@supports named-feature()` function for detecting support for the new behavior. I'm not sure exactly what the new behavior is (is it that elements transitioning to `display:none` stay in the top layer during the transition if they were in the top layer at the start of it?), but we'd presumably need to come up with a keyword for that behavior, and make an appropriate tradeoff between being concise and being descriptive. -- GitHub Notification of comment by dbaron Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/13200#issuecomment-3780885164 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
