Proposed Resolution: Allow a comma-separated list of custom property names in the @property prelude

Proposed Resolution: Change the TimelineTrigger interface to support multiple timelines in a top-level sequence

Proposed Resolution: Empty `<string>` should be parsed as invalid for `animation-name` and `<keyframes-name>`

Proposed Resolution: In addition to <string>, allow <syntax> in the 'syntax' descriptor

Proposed Resolution: Move listed features from Selectors level 4 to level 5, republish level 4 and get horizontal review on the way to CR.

Proposed Resolution: Rename two timeline-trigger-* properties

Proposed Resolution: The 'syntax' descriptor always returns the serialization of the syntax definition.

Proposed Resolution: timeline-trigger-range matches animation-range for omitted range ends
