Particle system 3D Start Rotation is not uniform with Transform Rotation when using Emit
How to reproduce:
1. Open the attached project from "case_1284152.zip"
2. Open scene "SimpelreproScene"
3. Select "Particle System" in Hierarchy and note 3D Start Rotation values in Inspector
4. Select "Quad" in Hierarchy and see Rotation under Transform in Inspector
5. Open scene "SampleScene"
6. Click on the ground (the green plane) and observe the console
7. Select "Test" in Hierarchy and toggle "Use Particle System" in Inspector
8. Click on the ground (the green plane) again and see the same rotation values in the console
Expected result: Upon clicking on the ground particles should be flat on the ground when using Particle System
Actual result: Particles on the ground are rotated not along with the ground
Reproducible with: 2018.4.28f1, 2019.4.14f1, 2020.1.10f1, 2020.2.0b9, 2021.1.0a2

Too risky to change the engine code.
