ArgumentOutOfRangeException is thrown for ReorderableList when nesting SerializedProperties
How to reproduce:
1. Open the user's attached project
2. In the Project window, navigate to Assets/Scripts
3. Select the Asset "Recurse Asset Array Error"
4. In the Inspector window, expand one of the "RecurseAsset Array Error-0" fields and attempt to add further nested arrays
Expected result: no errors are thrown
Actual result: error is thrown: "ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection."
Reproducible with: 2020.2.0b3, 2020.3.29f1, 2021.2.12f1, 2022.1.0b8, 2022.2.0a5
Not reproducible with: 2019.4.36f1, 2020.2.0b2
Notes:
1. In 2020.2, the error is thrown but nested arrays can be added further, while in later versions the error breaks the Inspector and nested arrays cannot be added
2. Related errors are thrown in some versions: "InvalidOperationException: The operation is not possible when moved past all properties (Next returned false)", "ArgumentNullException: Value cannot be null.", "NullReferenceException: SerializedObject of SerializedProperty has been Disposed."
