After https://commits.webkit.org/286869@main, the DOM implementation no longer destroys and recreates brand new DOM elements, instead managing the visibility via CSS content-visibility. This a good change, since we now do significantly less work, but need to make sure this property stays up-to-date. 2077074 1 webkit-bug-importer 2024-11-22 10:39:01 -0800 <rdar://problem/140428627> 2077075 2 tyler_w 2024-11-22 10:41:19 -0800 Pull request: https://github.com/WebKit/WebKit/pull/37036 2077276 3 ews-feeder 2024-11-23 07:25:52 -0800 Committed 287009@main (9da9cefb7d6d): <https://commits.webkit.org/287009@main> Reviewed commits have been landed.
