An object touching multiple Colliders in a compound Rigidbody causes strange spring force
Steps to reproduce:
1. Open the attached project (Bewildering Defiance of Physics.zip)
2. Open the Assets/Box Scene.unity scene
3. Press play and use the left and right arrow keys to move a box over a rigidbody that is held up by two spring joints, and is made up of a few box colliders
4. You should see the springy object will rise up when the yellow box is contacting multiple colliders on the springy object
Expected result: Springy object should not rise up
Actual result: Springy object rise up
Reproduced with: 5.3.7p4, 5.4.4p3, 5.5.0f3, 5.5.1f1, 5.5.1p4, 5.6.0b9

I am having a similar issue in my kart racing game. When the player kart with a rigidbody runs over a compound rigidbody collider, the physics causes it to shoot off into space at specific points. Checking this with the new Physics debug mode confirms that the colliders are correct, and that the physics is simply magical. This bug has been happening since 5.5 for me and is severely impacting the development of my project.
