Description Joey Arhar 2022-03-23 09:34:08 PDT 
This feature was added to the HTML spec here: https://github.com/whatwg/html/pull/7475
Here is an explainer: https://github.com/WICG/display-locking/blob/main/explainers/hidden-content-explainer.md

The "until-found" value for the hidden attribute should make the element content-visibility:hidden instead of display:none. 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.
