Created attachment 474950 [details] Repro If SVG foreignObject contains element with position: relative or with opacity, these elements are rendered incorrectly Steps to repro: * Open attached svg.html and notice how Elements of Actual result rows are misplaced. Additional info: * Can repro also with any old Safari * No repro with Chrome or FF * Developer tool highlight Elements in their expected location It seems that elements with position: relative or opacity are skipped from canvas resize for some reason.

It works fine in LBSE on WebKit ToT (293847@main) test via Minibrowser and matches Chrome Canary 137.
