System Information
Operating system: Windows 10
Graphics card: Nvidia GTX 1070

Blender Version
Broken:
2.82 Beta, 507a331f01, blender2.8, 2020-01-27

Short description of error
After undoing any change, every particle system in the scene resets its orientation axis. To fix this, you have to manually change the orientation axis to something else and back again. There may be other situations where the particle orientation gets reset, but this one is easily reproducible.

Exact steps for others to reproduce the error

Open the attached file
Set the ParticleSettings>Rotation>Orientation Axis to Global Z
Shift-A and add a cube (or any change at all to the scene)
Ctrl-Z
The particles are not longer aligned on the global z-axis.

Alternatively, it also breaks if you:

Open the attached file
Set the ParticleSettings>Rotation>Orientation Axis to Global Z
Save the file
Close and reopen the file

I tried to reproduce, file is too complex and doesn't work now.

Can you please check if this is still an issue in latest build?

I can still reproduce it with that file on the latest blender version. I've updated the description with this info and with clearer instructions. I know the current particle system is EOL, so this may just be a Won't Fix.
