Bug 1998544 [wpt PR 55877] - Allow <string> in the animation-name CSS property, a=testonly
Automatic update from web-platform-tests
Allow <string> in the animation-name CSS property
The animation-name property syntax allows both <custom-ident> and
<string> values. There were some doubts [1] about the serialization of
this property due to potential conflicts between the <string> values and
some identifies in the css-wide group.
The CSSWG resolution was to serialize this property as custom-ident when
possible, and as strings otherwise.
This CL aligns Chrome with Firefox and Safari as well as other minor
engines like Servo and Ladybird.
