The GameObject's rotation suffers from Gimbal Lock when Rotation Constraint is set on 2 axes
How to reproduce:
1. Open the user's attached "RotationConstraintBug.zip" project
2. Open the "SampleScene" Scene
3. Enter Play Mode
4. Press and hold the UP arrow key on the keyboard until both GameObjects stop rotating
5. Observe the GameObject on the right in the Game view while holding the Up arrow key
Expected result: The GameObject on the right doesn't flip (Doesn't suffer from Gimbal Lock)
Actual result: The GameObject on the right flips (Suffers from Gimbal Lock)
Reproducible with: 2018.4.27f1, 2019.4.10f1, 2020.1.6f1, 2020.2.0b3

"Workaround is to use the Animation Rigging package" yeah, but the Animation Rigging package suffers from the same problem.

The category of the bug should be “Animation”, since the rotation constraint is an animation component, I’m not referring to the rigidbody’s rotation constraint.

- Hinge Joint transforms are reset when toggling the "useMotor" property
- Motion Vector texture reports incorrect Mesh data when Mesh is coming from off-screen
Resolution Note:
This is due to current limitations in the rotation constraint.
Workaround is to use the Animation Rigging package.
