Rigidbody with interpolate setting set to Interpolate or Extrapolate does not follow parent transform position or rotation



Steps to reproduce:
1. Download and open Unity project from the google drive link
2. Open "Test" scene
3. Select Spaceship object in Hierarchy
4. Enter Play Mode
5. Press WASD to move
6. Observe child object's position as the spaceship is moving

Expected result: Child object with attached rigidbody follows the parent object's position/rotation, position stays at (0.0, 0.0f, 0.0f)
Actual result: Child object with attached rigidbody does not always follow the parent object's position/rotation when parent transform is modified

Alternate reproduction steps:
1. Open attached "" Unity project
2. Open Window-> General->Test Runner scene
3. Run _24SpaceshipGravitationalPullRigidbodyStaysInPlace test

Reproduced with: 2022.1.0a6
Didn’t Reproduce with: 2022.1.0a5, 2021.2.0b6, 2021.1.17f1, 2020.3.15f1, 2019.4.29f1

  1. Resolution Note (2022.1.X):

    The issue occurs because of a mixed hierarchy of 2D and 3D physics objects, which is not supported. The same issue could be reproduced by setting the Transform manually via Scripts
