SetParticles changes the rotation of first few particles when using Quaternion.LookRotation with specific upwards parameter

Shuriken

-

The upwards parameter has to be Vector3.down or Vector3.right.
Using Vector3.up, Vector3.left, Vector3.forward, Vector3.back does not reproduce the bug.

How to reproduce:
1. Open attached project "ParticleRotationBug.zip" and scene "SampleScene"
2. Enter Play mode
3. Observe Scene or Game view

Expected result: particles do not change their rotation3D
Actual result: first few particles change their rotation3D, resulting in flipped normals

Reproducible with: 2017.1.4p2, 2018.1.7f1, 2018.3.0a3

Workaround: do not use SetParticles with Quaternion.LookRotation upwards parameter
