Created attachment 472049 [details] Minimal repro Noticed that in Safari 18 beta 1-3 on macOS 14.6 (23G80). See the attached repro - when details element has content-visibility: auto - you cannot expand summary to see details. Works in Firefox, Chrome and worked in Safari 17. You can make details visible with Dev Tools if you force style invalidation (e.g. toggle some property). By the way, Safari 18 is missing from Feedback Assistant, only 16 and 17 are present.

Fixed by bug 157323 which started using content-visibility to implement showing/hiding of details contents. *** This bug has been marked as a duplicate of bug 157323 ***
