Physics.RebuildBroadPhaseRegions does not repopulate them with pre-existing shapes

Steps to reproduce:

1. Create a new 3D URP project
2. Add a plane with a MeshCollider on it
3. Add a script calling RebuildBroadphaseRegions on the plane
4. Add one disabled GameObject with a Rigidbody and a BoxCollider
5. Enter Playmode
6. Enable the disabled GameObject.
7. Observe it falling through the ground

Actual results: The GameObject falls through the plane without colliding with it

Expected results: The GameObject falls onto the plane and collides with it.

Reproducible with versions: 6000.6b1, 6000.5.0a5, 6000.3.0f1, 6000.0.67f1
