Created attachment 468576 [details] Broken behavior on Facebook Reels, TikTok, YouTube shorts Ever since I've upgraded to iOS17.1.1, I'm getting a broken behavior for `object-fit` in Safari on my iPhone: - `object-fit: contain` - the video starts either zoomed-in or out for a moment, then goes back to normal (sometimes it stays zoomed) - `object-fit: cover` - the video starts with a black flashing, then goes back to normal In the attached video, you can see the 2 behaviors on different apps: - Facebook Reels - `object-fit: contain` - the video starts zoomed-in, then goes back to normal - TikTok - `object-fit: contain` - the video starts zoomed-in/out, then goes back to normal - TikTok - `object-fit: cover` - TikTok tried fixing the bug, so instead of being zoomed, the video starts with a black flickering - YouTube shorts - `object-fit: cover` - the video starts with a black flickering

This should be fixed in iOS 17.4 beta. Please let us know if it's not, or if you are observing any other issues. *** This bug has been marked as a duplicate of bug 264293 ***

The issue seems to be resolved in Safari Technology preview(17.4). Is there any alternative fix we can apply until the safari release from our end?
