OnTriggerEnter gets called after reparenting a RigidBody



How to reproduce:
1. Open the user's attached project
2. Open the 'main' Scene
3. In the Hierarchy select the 'solid' GameObject
4. In the Inspector enable the 'Allow Reparent' checkbox (located under the Solid component)
5. Enter the Play mode
6. Observe the Console

Expected result: OnTriggerEnter and OnTriggerExit messages get logged only when the Sphere enters and exits the trigger volume at each end
Actual result: The OnTriggerEnter message gets logged constantly

Reproducible with: 2020.3.1f1, 2020.3.2f1, 2021.1.0a10, 2021.2.0a10
Not reproducible with: 2018.4.33f1, 2019.4.24f1, 2020.2.7f1, 2020.3.0f1, 2021.1.0a9

    In addition I have the problem, that OnTriggerExit sometimes is not called in this scenario (reparenting).
    Will this be addressed as well?
