Description

If there is a passive rigidbody which is child of another object and the parent object is being moved via script the passive rigidbody will not follow, even though it should. Because passive rigidbodies can be moved on their own via script I think this is a bug.
[passive rigidbody.zip](https://github.com/armory3d/armory/files/3827457/passive.rigidbody.zip)

**System**
Blender: 2.80
Armory: 2019.10.0 (Blender updated)
OS: Windows 10
Graphics card: GTX 1060 6gb

**Test File**
press h to move the parent(empty) of the rigidbody (the floor&cube) and it will not follow. But if you use h to move the floor on its own it will.

Research direction

Start with the attached passive.rigidbody.zip and reproduce the issue in Blender 2.80 using the documented H-key movement of the parent empty, then compare it with moving the floor directly. Trace the rigidbody parent-movement path and verify that the passive rigidbody follows its parent while retaining its independent scripted movement behavior.
