Cloth simulation is not natural when Time Scale is changed from one that's close to zero to 1
Steps to reproduce:
1. Open user's attached project
2. Open Project Settings window
3. Go to Time settings
4. Enter Playmode
5. Change Time Scale to 0.001 and then back to 1
Actual result: when Time Scale is changed from 0.001 to 1, Cloth moves way more than it should on such Time Scale
Expected result: when Time Scale is changed from 0.001 to 1, Cloth moves at the normal speed
Reproducible with: 2017.4.35f1, 2018.4.14f1, 2019.2.16f, 2019.3.0f3, 2020.1.0a16

(As an addendum to my last comment, I should note that the impulses resulting from the collision are far more muted after updating to 2019.4.13f1...)

I believe we were seeing this with collisions involving Physics.SphereCast (and brethren) as well.
The annoying thing is that the Physics interactions shouldn't have happened in the first place due to layer mask settings. It seems layer mask settings may be ignored by the Physics.*Cast APIs with very low time scales (and thus fixed time step values).
