Regression

No

Particle Bounds are displayed incorrectly until a change is made in the Particle System when the particles are generated by code

Shuriken

-

How to reproduce:
1. Open the attached 'project-1273773.zip' project
2. Enter Play mode
3. In the Hierarchy window select 'Particle System'
4. In the Scene window select 'Show Bounds'
5. Observe the bounds

Expected result: bounds match the particles (cube)
Actual result: bounds do no match the particles (distorted square)

Reproducible with: 2018.4.27f1, 2019.4.9f1, 2020.1.4f1, 2020.2.0b2

Note: making any single change in the Particle System game object (manually or by code) will reset the bounds to the right size/shape

    Resolution Note (fix version 2021.1):

    This was caused by a bug in Play that resets that systems procedural mode state causing the bounds to be incorrectly calculated. A workaround for this is to not call Play after calling SetParticles. Call Play first and then SetParticles.
