Inconsistent GameObject movement when changing the order of Constraint components
Reproduction steps:
1. Open the user's attached project "Constraint Order.zip"
2. Enter Play mode
3. Select the "constrained" GameObject in the Hierarchy window
4. Change the order of components in the Inspector window
5. Repeat step 4 (~5 times)
Expected result: The movement of the "constrained" GameObject depends on the order of components
Actual result: The movement of the "constrained" GameObject can be different even when the order of components is the same (Sometimes the "constrained" GameObject circles around the "center" GameObject while facing it, other times the movement is jittery and the "constrained" GameObject looks away from the "center" GameObject)
Reproducible with: 2019.4.38f1, 2020.3.33f1, 2021.3.1f1, 2022.1.0b16, 2022.2.0a10
Notes:
1. User reported that this might happen when loading/unloading scenes or adding/removing Constraints. Could not reproduce the issue that way.
2. Relevant documentation: "When updating the GameObject, Unity evaluates Constraint components from first to last as they appear in the Inspector window." (https://docs.unity3d.com/2021.2/Documentation/Manual/Constraints.html)
