Steps to reproduce:

1. Download and import attached project. (ReversedRotation.zip)
2. Play.
3. Select one of two particle system objects in hierarchy.
4. Place a Tick at 3D Start Rotation.

Expected result: Both particles rotates in same direction.
Actual result: After ticking 3D Start Rotation, particle starts rotating to opposite direction.

NOTES:
The same happens also when enabling Rotation over Lifetime -> Separate Axes. Also, Rotation by Speed -> Separate Axes.

Reproducible on: 5.4.0b1, 5.3.1p3, 5.3.0b1.
