ParticleSystem.Stop() doesn't stop ParticleSystem

When I call particles.Stop(), or particles.playOnAwake = false, the ParticleSystem still emits particles, and still returns true for particles.isPlaying.

What am I doing wrong?

public class ParticleTester : MonoBehaviour {
    void Awake() {
        ParticleSystem particles = GetComponent<ParticleSystem>();
        Debug.Log(particles.isStopped + " " + particles.isPlaying);

I’m having the same problem. Did you ever figure this out?
