The particle system prewarm flag is ignored when calling the Start function after the Stop function
Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Scenes/SampleScene” Scene
3. Enter the Play Mode
4. Press the “Space” Key to stop the particle system
5. While particle count is decreasing press the “Space” Key again
6. Observe the Game View
Expected result: The particle system spawns 150 new particles instantly
Actual result: The particle system starts creating new particles at the particle system's spawn rate

*Temporal workaround:* Call Particles.Clear() before calling Particles.Play() again. As long as NO particles are alive when calling Play, prewarm will work correcly.
After calling stop there may be a few seconds where there are active particles in the system, depending on their lifetime. If play is called before those last particles die, the system will start spawning as described, but without instantly spawning prewarmed particles to match a fully prewarmed particle system.
