Rotation of emitter doesn't affect spawned particles

Describe the bug
Rotation part of ParticleEffect
's GlobalTransform
does not rotate velocity of spawned particles. Seems like https://github.com/djeedai/bevy_hanabi/pull/43 should've fixed that, but maybe there was a regression ? Or I'm misunderstanding something.
Expected behavior Particles rotate towards emitter's own rotation.
