Prefab changes are not applied and an error occurs when changing fields that have SerializeReference attribute

Serialization

-

How to reproduce:
1. Open the attached project (SeralizedRefBug.zip)
2. Select the GameObject in the Hierarchy window
3. In the Inspector add any value to the list of SerializationBug Component
4. In the Component Context Menu select 'Modified Component' -> 'Apply To Prefab 'GameObject'

Expected result: the newly added value gets saved to the GameObject prefab
Actual result: the changes are unsaved and an error appears in the Console window

Reproducible with: 2019.3.10f1, 2020.1.0b5, 2020.2.0a7
Could not test with: 2017.4.39f1, 2018.4.21f1 (UnityEngine.SerializeReference not introduced)

Notes:
Clicking the 'Apply All' button in the Overrides drop-down window at the top of the Inspector works as expected
