GameObject with Character Controller Component fails to detect Colliders when its Transform is changed
How to reproduce:
1. Open user attached project "UnityBug_PhysicsIgnoringCollisions.zip"
2. Enter Play Mode
3. Let the game run and observe for about 20 seconds
Expected result: "Character" Game Object always detects Colliders below itself
Actual result: "Character" Game Object does not detect Colliders below itself
Reproducible with: 2019.4.29f1, 2020.3.16f1, 2021.1.17f1, 2021.2.0b7, 2022.1.0a5
Note:
- When the game gets paused, in the Hierarchy window, reenabling active "Chunk" GameObjects resolves the issue for a while, but the issue happens again. Reenabling active "Chunk" Game Objects for the second time fixes the issue entirely and the issue will not reappear for the remainder of the session
- "CharacterControllerTest.cs" contains all the Tranform changing logic

Resolution Note:
The bug is no longer reproducible on 2023.1 and 2023.2 Unity streams. It was likely fixed by the general Transform Sync improvements that are unfortunately not backportable.
