How to burst a particle system twice?

Hello. I have a bit of problem getting a simple burst particle system to work. To reproduce the issue, create a new Particle System, set Duration and Start Lifetime to 1, then under Emission set Rate to 0 and add a Burst with the default settings. Disable Looping and Play On Awake.

Then, I’d like to drive the burst through code. A simple demonstration could be per mouse click.

using UnityEngine;
using System.Collections;

public class PlayParticles : MonoBehaviour
{
    void Update ()
    {
        if (Input.GetMouseButtonDown (0)) {
            var ps = GetComponent<ParticleSystem> ();
            ps.Stop ();
            ps.Clear ();
            ps.Play ();
        }
    }
}

I would expect that on each mouse click, a burst is played. This works until the particles disappear. After particles have disappeared, calls to Play does nothing. However, if I change simulation space to World, then Play works as intended. The problem is that I require local space simulation.

How can I make the particle system play more than once, after the initial particles have disappeared?

I’m using Unity 5.3.2f1

Works with 5.3.4
