Rigidbody stays unstable if it is placed on top of another Rigidbody which has Animator



Steps to reproduce:

1. Open attached project ""
2. Open scene "Repro"
3. Run the scene
4. Notice that structure in the left, called "Stacked on top of animated" is doesn't become stationary when the structure on the right does

- The base of left structure has Animator attached which has animation. That animation has keyframes set of position and rotation of its child objects but values aren't animated and are always the same.
- Removing either position or rotation keyframes make this bug go away
- Object which has rotation animated is completely empty game object (only has Transform component) and therefore shouldn't affect other objects by any means

Not reproducible: 5.2.4f1
Reproduced with: 5.3.0a3, 5.3.4f1, 5.4.0b11
