Currently, if you background and foreground Safari on iPad while on YouTube, you will get a different page layout compared to what was displayed before the backgrounding process. Since the viewport sizes are the same one would expect there to be no difference in the page layout. This is due to a ResizeObserver callback using requestAnimationFrame to execute some logic to reinitalize the ResizeObserver, but the observer is ultimately put into a bad state due to the quick viewport size changed. By silencing ResizeObservers during this process we should not trigger this behavior and reintroduce the expected page layout again. * Source/WebCore/dom/Document.cpp: (WebCore::Document::updateResizeObservations): * Source/WebCore/page/Quirks.cpp: (WebCore::Quirks::shouldSilenceResizeObservers const): * Source/WebCore/page/Quirks.h: Canonical link: https://commits.webkit.org/265603@main _______________________________________________ webkit-changes mailing list webkit-changes@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-changes
