Mesh Particle SubEmitter Rotation Problems

Attempting to create some mesh particle effects using the shuriken system. However I can't seem to figure out how to fix the emission direction of subemitters. The emission shape is a cone, and upon selecting it shows the cone pointed in the correct direction, if I rotate the subemitter when it is emitting, the particles do rotate to the correct direction, but then the next emission goes back to emitting along the +z direction.

I have tried changing both the primary particle system, and the subemitter to both world/local simulation space, and all combinations of such, and it doesn't have any effect.

Any help is appreciated.
