Description yisibl 2023-02-23 03:15:02 PST 
I tested and found that Safari loses animation in the shorthand property.

In this demo[1], the 1nd and 3th ones lose animation, and the 5th one has no background color.

CSS custom properties have been released in Safari 16.4 beta, is there still time to merge it into that version once the bug is fixed?

We are aware that this is a valuable bug fix for Safari 16.4. However, we cannot comment on future Safari releases.
