Changes in Output Inspector surface options do not mark the asset as dirty, and after undoing edits to Particle Options values the graph is marked as dirty

Steps to reproduce:

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

Actual results: 

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

Expected results: 

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