Support CSS @property at rule

[wailingwizard]

I use this a lot for CSS animations and other advanced CSS work. It works everywhere but Firefox which is really disappointing. I'd really love to see Firefox support the CSS @property at-rule in the near future!  https://developer.mozilla.org/en-US/docs/Web/CSS/@property

Hi, thank you for reaching out!

Implementing @property at-rule is part of Interop 2023 -  a cross-browser effort to improve the interoperability of the web (https://wpt.fyi/interop-2023)

The plan is to support this till the end of 2023
