Reproduction steps:
1. Open the “NestedListOfSerializeReferences“ project
2. Open the “SampleScene“ scene
3. Select the “Test” GameObject
4. In Inspector add an element to the list inside the “Script Compilation 1” foldout
5. Change any value of the added element
6. Add an element to the list inside the “Script Compilation 2” foldout
Expected result: the value changed only for the element in step 5, and the element added in step 6 is not empty
Actual result: all elements had their values changed in step 5, and the element added in step 6 is empty
Reproduced in: 2021.3.21f1, 2022.2.10f1, 2023.1.0b7, 2023.2.0a6
Could not test in: 2020.3.46f1 (compilation errors)
Reproduced using: macOS 13.2.1 (Intel), Windows 10 (by the reporter)
Reporter’s note: the desired behavior would be showing a “+” button with a small triangle. The said button would ask to select a fitting type.
