rotateX() rotateY() - unstable on version 13 to 15 (current) - workaround exits

[imsys]

What information was incorrect, unhelpful, or incomplete?

rotateX() and rotateY() is not well supported in Safari version 13 to 15. (current) It has a regression bug. (I also sent a bug report to the Safari Team)

What did you expect to see?

I would expect to see a note in rotateX() rotateY() in Safari and Safari on iOS mentioning the workaround fix.

Did you test this? If so, how?

I added tilt.js to a customer website and it had bugged out in his iPad. As I don't own any Apple device, I had to use browserstack to debug it. It turns out that if there is a single element {position: sticky; z-index: -1;} in the page, it somewhat creates a conflict with the rotateX() rotateY(). The way I found to fix it is by adding -webkit-transform: translateZ(0) to the rotated object parent.

Someone else got a similar problem, but somewhat different on StackOverFlow: https://stackoverflow.com/questions/18146511/bug-in-css3-rotatey-transition-on-safari
I don't have the patience to debug that problem, but the solution to that was the same. (-webkit-transform: translateZ(0))
Seeing their problem doesn't have a position: sticky object, it makes me think there are many things that could trigger the bug.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

I think this bug could be related to #6637
