ParticleManager in scaled Container positions subsequent emitters wrong

[mariogarranz]

I could replicate this issue in this CodePen

In this example I create one ParticleEmitterManager and it into a Container that had its scale modified.

Then I add 3 ParticleEmitters to this ParticleEmitterManager, all of them with the exact same settings, but everytime a new ParticleEmitter is added, some offset is added to its positioning and scaling, so in the end you can see all 3 of them in different spots and scales.

This seems like a bug to me, but maybe I got something wrong?

My game uses a container with a scale for the board of the game and it's being impossible to have the particles display properly over it, unless I use 1 ParticleEmitterManager for each ParticleEmitter, which seems too overkill.
