What specific section or headline is this issue about?

No response

What information was incorrect, unhelpful, or incomplete?

The keywords to use in random() and how just specifying a dashed ident have changed, as per w3c/csswg-drafts#13132 (comment) resolution

What did you expect to see?

The random cache key values are now element-scoped, property-scoped and property-index-scoped which are not present in the current documentation.

Do you have any supporting links, references, or citations?

Do you have anything more you want to share?

Safari 27 will ship an updated implementation that uses these new keywords. The implementation in Chrome Canary has not been updated (yet).
