Physics.ComputePenetration returns false for some collider combinations when collision depth is small
Steps to reproduce:
1. Open project (PhysicsComputePenetration WithMeshRenderer.zip)
2. Open the Main scene
2. Select collider and CapsuleWithMesh object
Expected result: Physics.ComputePenetration returns true on all collisions depth amounts
Actual result: Physics.ComputePenetration returns false on a small amount of collision depth
Reproducible with: 2017.4.31f1, 2018.4.5f1, 2019.1.13f1, 2019.2.0f1, 2019.3.0a11
Not reproducible with: 2020.2.0b1
Note: This happens with Mesh Collider and Capsule Collider combinations

That's not an acceptable resolution. The code have to be reliable in any case and especially when the mesh collider is generated by the Editor.

Resolution Note:
This issue happens to be a rare one that is related to the particular triangulation in this mesh, so we'd suggest re-triangulating it so that it's a more regular one (meaning triangles being of comparable size, avoiding long thin ones as well as very large ones too).
