Created attachment 413580 [details] Reproducable Xcode project Safari Web Extension in Safari 14: Elements in the bottom of big popover (>=441px height) behave strange. For example when I hover on such element the focus style and cursor constantly blink, it seems as if I move mouse really fast over element up down. This not happen for elements located before this threshold (above 441px height). Check video https://share.getcloudapp.com/qGuvddqj . I also attached reproducable Xcode project. I also noticed that something strange happening with layout recalculation in browser_action popovers. When you try to use libraries like react-textarea-autosize (auto resize textarea elements) - they work really slow, especially if you have more than one on a page. If I check Performance tab in Developer tools there 46% and 43% of processing time spend on Layout and Styles respectively. I suppose hover behaviour and layout recalculation problems I mentioned have something in common, so I decided to put them in one ticket.
This may looks like a minor bug, but in real app when it have many elements everything feel junky. This bug prevent me to release my web extension for Safari 14. Please help! I send ticket in Macos Feedback tool few weeks ago, no response.

Sorry no update?
We are also experiencing this issue @ Bitwarden after migrating to Web Extensions. Any update or movement from Apple's side?

Also when Safari in full-screen mode flickering doesn't happen. I attached a video
This tiny window size has been an awful experience using Bitwarden with Safari for a year now. Chad also mentions this on 2021-07-15 and there's been zero traction on the issue. WHEN is this going to get fixed by Apple? Still an issue on Safari 15.2. Thanks!
