User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

Go here:
https://smartslider3.com/bugs/firefox/perspective1/
and hover over the element.

Actual results:

During a "transform" CSS code created rotation, a weird skewing happens.

This seems to happen, because there are multiple parent elements with "perspective" CSS codes.

Expected results:

There shouldn't be any skewing. The same result should happen, as what happens by adding this CSS code:
*{
perspective:none!important;
}

Or you can compare to Chrome too.

The Bugbug bot thinks this bug should belong to the 'Core::Web Painting' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
