When the browser searches for text via find-in-page or ScrollToTextFragment, it should also search for text in hidden=until-found elements. If find-in-page or ScrollToTextFragment want to scroll to a match inside a hidden=until-found element, it should remove the hidden attribute from the element and fire the "beforematch" event on it in order to reveal the match. 1854229 1 webkit-bug-importer 2022-03-23 10:01:02 -0700 <rdar://problem/90706206> 2084906 2 m.goleb+bugzilla 2025-01-05 04:28:09 -0800 As stated in https://bugzilla.mozilla.org/show_bug.cgi?id=1761043, Wikipedia uses this attribute now, which means find in page works much better in Chrome on Android than on iOS. This is something I am hitting on a daily basis as an iOS user. 2084958 3 ntim 2025-01-05 16:22:31 -0800 Bug 228843 can probably be used as inspiration if someone wants to hack this. 2095109 4 schaepp 2025-02-17 00:11:16 -0800 I've found one more use case where hidden=until-found is very helpful which I described here: https://schepp.dev/posts/rethinking-find-in-page-accessibility-making-hidden-text-work-for-everyone/ I'm aware that this feature is part of Interop 2025 via <details> element, but maybe we can get this quicker than end of this year? 2126231 5 ntim 2025-06-27 01:40:49 -0700 Pull request: https://github.com/WebKit/WebKit/pull/47284 2128233 6 ews-feeder 2025-07-07 12:39:43 -0700 Committed 297073@main (4f12f2494d1c): <https://commits.webkit.org/297073@main> Reviewed commits have been landed.
