Reproduction steps:
1. Open the attached “AB Test” project
2. Open “SampleScene”
3. Enter Play mode
4. Observe the yellow text
Expected result: the position numbers do not change - the articulation bodies are not moving
Actual result: the position numbers change - the articulation bodies are moving
Reproducible with: 2020.3.46f1, 2021.3.22f1, 2022.2.13f1, 2023.1.0b10, 2023.2.0a8
Reproducible on: macOS Catalina 10.15.7 (Intel), Windows 10 (by the reporter)
Notes:
- Also reproducible in Standalone Player
- If the collider is on a root articulation body it moves even if "Immovable" is checked, but only if it's a box collider
- The issue happens when the position or rotation of the collider is constantly changing
