Regression
Yes
Particle System bursts twice when instantiated at a runtime
How to reproduce:
1. Open attached Unity project "BurstBug.zip (4.3 MB)" (attached to additional email)
2. Load "Bug" scene
3. Enter the Play mode
4. Press "Burst" button
Actual Result: ParticleSystem emits burst twice when added at a runtime.
Expected Result: ParticleSystem emits burst once.
Regression first introduced in: 2017.1.0a3
Reproducible with: 2017.3.0a1, 2017.2.0b4, 2017.1.0p2, 2017.1.0a3
Not reproducible with: 5.6.2p4, 2017.1.0a2
Notes:
* If the same prefab is added to the scene in edit mode, it works correctly on play mode.
* In the 5.5 version either in edit and play modes multiple bursts occur.

I somehow solved the problem by using "Stop action" in particle system to disable particle instead of using my own script.
Also, use sub-emitter to emit child particles, disable "emission" in particle system of any child object, this also solved the problem for me.

Still getting this in 2017.2.0f3
When I play a particle system it always burst twice.

Getting this also in Unity 2017.1.0p1-p5
It's really a gamebreaker if you depend on your ParticleSystems to spawn one mesh particle
it happens for existing particle systems too, even when not instantiating them from code as well!
