Expected result: UnityEvent listeners remain unchanged
Actual result: All UnityEvent listeners that are inherited class members are unassigned

I would like to confirm a variant of this issue that is very hard to reproduce happens on Unity 6000.1.10f1 up to 6000.1.13f1. Some persisted event listeners get randomly lost but due to other editor actions not yet determined.
Still trying to find a pattern.
Hopefully this will also fix this adjacent and possibly related issue.
