background:none is applied as background-image:none in Safari

[Artur-]

Describe the bug

.nobg { background: none !important;} 
.nobg {background: blue; }

shows a blue background in Safari.

To Reproduce
https://artur.app.fi/stylesheet-polyfill-bug3.html

Expected behavior
The element should have the defined CSS rules set and thus no background.

Screenshots
Styles in Chrome

Styles in Safari

Additional context
Not only is background replaced with background-image and background-color. It also seems like !important is lost

@Artur- can you confirm this is fixed?

Amazingly enough it seems all tests that pass with 2.4.16 pass also with 3.0.4
