Animator component properties should not be animatable, but they are.
(Animator, Apply Root Motion, Update Mode, Culling Mode)

...the properties are created in the animation clip (bad), does not work and creates a missing property error (yellow property).
see attached image.

repro:
- Import attached package or create a clip on a cube
- Set AW in Rec mode
- animate any Animator component property (ex: Animator Enable, Apply Root Motion, etc.)
result: property is added to clip
expected: no property is added to the animation clip.

This is a regression.
