[webkit-dev] Request for Position: Auto-expanding details elements

[Joey Arhar]

Hello WebKit devs,

I am implementing the auto-expanding details elements feature in Chromium,
and I would like to hear WebKit's position on the feature.
Chromestatus entry: https://chromestatus.com/feature/5032469667512320
Spec:
- https://github.com/whatwg/html/pull/6466
-
https://html.spec.whatwg.org/multipage/interaction.html#interaction-with-details
Explainer:
https://github.com/WICG/display-locking/blob/main/explainers/auto-expanding-details-explainer.md
WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=228843

Today, users can’t search for content inside details elements when they are
closed. If the user wants to search the page for content inside details
elements with find-in-page, then they have to manually expand every details
element in the page before they use find-in-page.

This feature makes the hidden contents of closed details elements
searchable by find-in-page and makes the browser automatically open them
when trying to scroll to their hidden contents so that users can always
search inside them.

In addition to find-in-page, this feature should also work for Element
fragments (navigating to a hash with an element id) and
ScrollToTextFragment in order to make content hidden inside <details>
elements more findable, searchable, and shareable.
