After review we have elected not to address this issue at this time.

2022.1 has reached end of life so the issue will be fixed in a newer version.

To reproduce:
1) Open attached project and scene in it
2) Play it
3) Select "TwoProblems"
4) In scene view, start rotating it by y axis

Expected: In console, joint.angle value stays the same as it is only parent changing rotation, not the child
Actual: Angle changes upon rotating

Reproduced: 5.4.3p4, 5.5.2p4, 5.6.0f2, 2017.1.0a5
