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

@smfr when will this land in safari? is it already released?
Comment 4 Alexey Proskuryakov 2024-02-13 10:53:29 PST 
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.

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?
Comment 6 rt12148 2024-02-13 21:55:24 PST 
The issue is also happening in MacOS safari. not just iOS in 17.3.1
