How to reproduce:
1. Open the attached "IN-140539" project
2. Open the "SampleScene"
3. Drag and drop the "Space" Prefab from the Project window into the Hierarchy to create a Prefab instance
4. Select the "Space" Prefab instance
5. In the Inspector, change its Transform Rotation Y value to 300
6. Right-click the Rotation property name in the Inspector and select "Revert"
7. Observe the Rotation Y value in the Inspector
Actual Result: The Rotation Y value becomes 360 instead of 0
Expected Result: Rotation Y value becomes 0 (restoring the exact original Prefab Asset value)
Reproducible with: 2023.1.0a3, 6000.0.74f1, 6000.3.15f1, 6000.4.6f1, 6000.5.0b6, 6000.6.0a4
Reproducible on: Windows 11
Not reproducible on: No other environments tested
Notes:
- You don't need to set the Y rotation value to exactly 360 manually; it just has to be closer to 360 as compared to 0 for this Euler angle equivalence issue to occur during the revert
- X and Z rotation value performs the same way.
