Unrelated array elements are overwritten with values from other elements when a removed array element is applied via "Modified Component > Apply to Prefab"

How to reproduce:

1. Open the attached “IN-152221” project
2. Open the “SampleScene” scene
3. Open the “Git Bash” CLI
4. In the opened “Git Bash” console, type “cd <path to the project folder>” and press “Enter” key
5. Type “git init && git add -A && git commit -m baseline” and press “Enter” key
6. In the Hierarchy tab, select “Some prefab” GameObject
7. In the Inspector tab under “Animator Event 2 (Script)”, expand “Events”
8. Under the “Events”, select 3rd element (“VFX/Sprint/ON”)
9. Go to the bottom of the “Events” elements and click “-” (delete) button
10. In the Inspector tab, right-click on the “Animator Event 2 (Script)” > “Modified Component” > “Apply to Prefab ‘Some prefab’”
11. Save the changes (Ctrl + S)
12. In the “Git Bash” console, type “git diff – "Assets/Some prefab.prefab"“ and press “Enter” key
13. Observe the result in the “Git Bash” console

Actual result: The “Override/YLW/Hammer” element, which was not edited, has parameter values replaced with values belonging to other elements in the array
Expected result: The selected element is removed, with every other array element unchanged

Reproducible with: 6000.0.1f1, 6000.0.82f1, 6000.3.23f1, 6000.5.0a3
Not reproducible with: 6000.5.11f1, 6000.6.0f1, 6000.7.0a6
Fixed in: 6000.5.0a4

Reproducible on: Windows 11 Enterprise (25H2)
Not reproducible on: No other environments tested

Note: The bug reproduces when any element of the “Events” array is deleted (not just “VFX/Sprint/ON”)
