AX: reports of Reduce Motion not working in iOS 14.5 (18E… and 18F…)

Seems to work on most of the WebKit blog examples and layout test cases.
https://webkit.org/blog-files/prefers-reduced-motion/prm.htm

But the demo on the MDN page does not work:
https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion

I will post other URLs as the bug reporter shares them.

Media feature appears functional but is returning the inverse of what it should. If you turn OFF reduce motion, the media query matches as ON.

This appears to be broken already on iOS 14.4 (18D).
Comment 5 Antoine Quint 2021-04-27 00:31:52 PDT 
No, sorry, it was working in iOS 14.4.
