"Invalid iteration" when selecting multiple objects and adding elements to the list through multiple Inspectors

Inspector Framework


Reproduction steps:
1. Open the attached "" project
2. Open the "SampleScene" Scene
3. Open two Inspector windows
4. Select the "First" and "Second" GameObjects
5. Go to Inspector -> "Some Array (Script)" Component -> Test
6. Add at least two elements to the list
7. In the second Inspector add an element to the list

Expected result: There are no error messages and the UI of the list is consistent
Actual result: "Invalid iteration - (You need to stop calling Next when it returns false)" error message is thrown and the "Some Array (Script)" Component starts flickering or UI of the list becomes inconsistent

Reproducible with: 2020.3.29f1, 2021.2.12f1, 2022.1.0b8, 2022.2.0a4
Couldn't test with: 2019.4.36f1 ("Add to the list" button is not introduced)

- The error message and flickering appear only in 2022.2.0a4
- Flickering appears only after adding more than two elements to the list
- In the versions below 2022.2.0a4 the amount of elements or the UI of the list is inconsistent

  1. Resolution Note (fix version 2022.2):
