Rigidbody recalculates its center of mass when moving its child Trigger Collider

--

-

Reproduction steps:
1. Open project “My project (1)”
2. Open “SampleScene”
3. Enter Play Mode
4. Select “Parent” GameObject from the Scene Hierarchy and lock the Inspector Window
5. Select “Cube” GameObject and move it up and down through the Scene View
6. Observe the locked Inspector Window

Expected results: the “Parent” Transform's position is not changing
Actual results: the “Parent” Transform's position is changing every time the child Trigger Collider moves

Reproducible with: 2020.3.46f1, 2021.3.21f1, 2022.2.12f1, 2023.1.0b9, 2023.2.0a7

Reproducible on: macOS Catalina 10.15.7 (Intel), Windows 10

Note: this is expected for regular Colliders but not for Triggers since they do not contribute to the mass distribution
