How to reproduce:
1. Open the attached project's Scene labeled "SampleScene"
2. Enter the Play Mode
3. Press the "Space" key
4. Open up the Profiler Window (Window->Analysis->Profiler)
5. In the Profiler, search for "ParticleSystem.Prewarm"
Expected result: "ParticleSystem.Prewarm" is not found
Actual result: Simulating Particle System in Late Update causes a prewarm
