What specific section or headline is this issue about?

constituent properties

What information was incorrect, unhelpful, or incomplete?

Several shorthand properties, like animation accept a limited number of properties while being reset-only for other properties. We should include a section after ### Constituent properties that lists the reset-only properties that are reset by the shorthand.

What did you expect to see?

the animation-trigger-* properties listed as reset-only sub-properties of animation
