Summary Don't attempt to animate invalid CSS properties

Reported 2018-12-12 09:38:12 PST
Inherited animation properties can cause child elements to think they need to animate CSS properties that they do not support, leading to nullptr crashes. Instead, recognize that CSSPropertyInvalid is a potential requested animation property, and handle it cleanly (much like Animation::AnimateUnknownProperty is already handled).
