[Backport] [UIToolkit] ArgumentOutOfRangeException is thrown when adding/removing elements from a List in the Inspector

--

-

How to reproduce:
1. Open the attached "case_1418688" project
2. Open the "SampleScene" Scene
3. Select the "Repro" GameObject in the Hierarchy
4. Click the "+" button under the "Component -> Colors" List in the Inspector to add a new element to that List

Expected result: A new element is added to the "Colors" List without any errors
Actual result: A new element is added to the "Colors" List with the "ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection." error thrown in the Console log

Reproducible with: 2021.3.1f1, 2022.1.0a16, 2022.1.0b16, 2022.2.0a3
Not reproducible with: 2022.1.0a1, 2022.1.0a15, 2022.2.0a4, 2022.2.0a10
Couldn't test with: 2019.4.38f1, 2020.3.33f1 (the project isn't compatible)

Notes:
- The error is thrown after adding/removing the 7-8th and more element
- In some versions, the "SerializedProperty Colors.Array.data\[INDEX] has disappeared\!" error is thrown instead, where INDEX is the element position index in the List
