How to reproduce:
1. Open the attached "IN-132316_Repro" project
2. Open scene "Scenes/SampleScene"
3. In the Scene Hierarchy, select both Script A and Script B
4. In the Inspector, add or remove an element from the "Targeted Objects" array

Actual result: No warning is thrown and the array sizes of both objects are modified
Expected result: A warning is thrown informing the user that both objects will be modified

Reproducible with: 2022.1.0a4, 2022.3.71f1, 6000.0.66f2, 6000.3.6f1, 6000.4.0b6, 6000.5.0a7
Not reproducible with: 2021.3.58f1, 2022.1.0a2
Could not test with: 2022.1.0a3 (Can't open the project or create a new one. License errors are thrown.)

Reproducible on: MacOS 15.7.3 (User), Windows 11
Not reproducible on: No other environment tested

Notes:
- The warning is thrown correctly if trying to remove an object that is not the last one in the array
