Steps to reproduce: 1. With an iPad 2. Launch Safari 3. Go to https://YouTube.com/ (if you have history, YouTube will have a 3 columns layout). 4. Home out of Safari to be back on the ipad desktop 5. Wait a few seconds 6. Bring back Safari again Before the Quirk shouldSilenceResizeObservers Youtube home page was on 1 column when bringing back Safari After the quirk shouldSilenceResizeObservers Youtube home page has the 3 column like before. That said, 1. when deactivating Site Specific Hacks on iPad to remove the Quirk, it doesn't seem to change the behavior. 2. It's difficult to test on my current device as having Web Inspector opened seems to stall Youtube.com So I'm on the fence. The initial Quirk bug seems to not reproduce, but at the same time I'm not 100% sure the Web Inspector has an impact on the test. 2059166 1 webkit-bug-importer 2024-09-10 19:54:02 -0700 <rdar://problem/135770639>
