Short description of error
Rendering hair in workbench doesn't work if using standard Render Animation -- bpy.ops.render.render()

However when clicking the Display Render View in viewport and setting view>viewport animation -- bpy.ops.render.opengl() -- it works.

I'm guessing these are different in that a separate operator is used? however the results are so similar i assume they are using the same engine?.

Exact steps for others to reproduce the error
Use the file attached.
test_hair_workbench_renders.blend

OR

Create new file and create a sphere then animate it.
Add hair to it, turn dynamics on and cache
Render Ctrl+F12 -> review result
Render openGL -> review result and make comparison
