[PhysX] Articulation joint Motion - "Limited" can be broken by force

Physics

-

How to reproduce:
1. Open the user's attached project ("ArmRobot.zip")
2. Enter Play mode
3. Aim at the robot arm and shoot spheres clicking "Space Bar" until the "Base" is forced to rotate and spin out of control

Expected results: The "Base" of the robot arm does not rotate because Motion is set to "Limited"
Actual results: The "Base" of the robot arm is forced to rotate and spins out of control

Reproducible with: 2020.1.15f1, 2020.2.0b13, 2021.1.0a7
Couldn't test with: 2018.4.29f1, 2019.4.15f1 (PhysX didn't have Articulation Bodies yet)

  1. Resolution Note:

    Articulation is pushed into an unsolvable configuration by an incoming large rigidbody.
