SerializeReference field from ScriptableObject loses value when deleting last array item and then pressing undo
Reproduction steps:

3. In the Inspector window right-click on "Element 0" and select "Delete Array Element"

Unfortunately this breaks my project. How can I avoid using SerializeReference?
Moreover if I put a custom property drawer on the object I made the array of, it just makes Unity 2020.2.2 quit without any usable information.
