I think this already matches the standard property, so I don't think there's any reason not to just unprefix it (with an alias)?

Is there a stable enough spec whose behavior we match?

I think this is mostly missing the <percentage> syntax to match the standard: https://drafts.csswg.org/css-size-adjust/#adjustment-control
Oh wait, actually no, we do support the percentage syntax.
We should definitely attempt to make the property animatable as one of the WPT show (and the spec as well).
