-

To reproduce:
1. Open attached Unity project "ParticleCollisionBug.zip"
2. Open "demoscene" scene
3. Go into Play mode
4. Inspect the particles colliding and bouncing
5. Click "Mirror" which sets particle system's x scale to -1

Expected result: The particles should collide with the platform
Actual result: with the scale set to negative, particles ignore the collision (see attached gif "particles.gif")
