Lock axis does not work with Emitter Rotation

Screen alignment is set to PSA Rectangle, Pivot Offset is (0.5, 0.0), Lock Axis is locked to Rotate X, and Local Space is checked on.

So this gives me a sprite going down the X axis and behaving similar to a beam. Now I want to pitch it up a little, rotate it slightly, etc. I was hoping the Emitter Rotation under the Required module would allow me to do this but it does not affect the sprite at all. However, when I place the emitter in the world and rotate it, it behaves the way I would expect.

Is there any way to make the Emitter Rotation behave the same way as if you placed the emitter in world?

Thanks!

NOTE: I really do NOT want to use Velocity based sprites to achieve what I want because they behave strangely if you slomo the game or have bad framerate.
