When a page is updating attributes on many SVG elements, but is not making changes that require a restyle on those elements, we can spend a lot of time hashing to store and look up the Style::Update associated with an element. We could track the "SVG renderer update is needed" state using a Node flag instead, but continue using the Style::Update mechanism for root tracking, to reduce the overhead. 1875105 1 webkit-bug-importer 2022-06-09 14:00:54 -0700 <rdar://problem/94756741> 1875106 2 heycam 2022-06-09 14:20:24 -0700 Pull request: https://github.com/WebKit/WebKit/pull/1430 1875698 3 heycam 2022-06-13 22:01:30 -0700 Pull request: https://github.com/WebKit/WebKit/pull/1492 1875699 4 heycam 2022-06-13 22:04:38 -0700 Pull request: https://github.com/WebKit/WebKit/pull/1493 1875877 5 ews-feeder 2022-06-14 15:00:42 -0700 Committed r295539 (251544@main): <https://commits.webkit.org/251544@main> Reviewed commits have been landed.
