Particle system with distance emission do not appear when the parent object is moving



Particle system does not emit if its parent object is moving with RigidBody.MovePosition().

Reproduction steps:
1. Open the attached project;
2. Enter a play mode;

Expected results: particles should appear in the game view even if its parent is moving;
Actual results: particles do not emit.

Reproduced on: 5.5.0f3, 5.6.0f3, 2017.1.0b1.
Not reproduced on: 5.4.4p3.

By design: using MovePosition to move a non-kinematic RigidBody is incorrect and you should be setting the velocity directly. Move Position is more for when you want to teleport an object and don't want the velocity to be updated.
