Grab RenderTexture from a particle shader is executed even if the Particle System is not emitting
How to reproduce:
1. Open the attached "BugParticleGrabPass.zip" project
2. Open scene "SampleScene"
3. Enter Play mode
4. Open and enable the Frame Debugger
Expected results: Grab RenderTexture calls should not be executed because neither of the two Particle Systems are emitting
Actual results: There are two Grab RenderTexture calls
Reproducible with: 2017.4.29f1, 2018.4.2f1, 2019.1.6f1, 2019.2.0b5, 2019.3.0a5

RESOLUTION NOTE (FIX VERSION 2019.3):
We have only been able to figure out how to prevent the Grab Pass if the system is not playing (i.e. is in the stopped state). It is difficult/risky for us to try and filter out systems that are playing but contain no particles. We may revisit this in the future.
