Steps to reproduce:

Open the attached package
Open VFX and if it is marked as dirty save it
Select Output and in Output Inspector change Surface Type from Opaque to Transparent
Observe that VFX is not marked as dirty
Then tick Cast Shadows bool in Output Inspector > Particle Options dropdown
Undo the change
Observe that VFX is marked as dirty even if you've undone the change

Actual results:

VFX isn't marked as dirty after material property changes in the Output Inspector.
After a setting is changed in Output Inspector > Particle Options and then undone, the asset remains in a dirty state

Expected results:

VFX is marked as dirty after material property changes in the Output Inspector.
After a setting is changed in Output Inspector > Particle Options and then undone, the asset does not remain a dirty state
