How to reproduce:
1. Open the attached “IN-97074” project
2. In the Project tab navigate to Game/Assets/Villagers and select the “VillagerBase” prefab
3. In the Inspector tab find “Villager Behaviour” Script Component
4. Change any values in the Script Component
5. Click on the Scene view/Game view/Hierarchy tab to unselect prefab
6. Enter Play mode
7. Select the “VillagerBase” prefab again
8. Observe the changed values

Expected result: Values are retained
Actual result: Values revert to old ones

Reproducible with: 2022.3.12f1 (4fe6e059c7ef), 2022.3.60f1, 6000.0.43f1, 6000.1.b11, 6000.2.0a7
Not reproducible with: 2021.3.49f1, 2022.3.11f1

Reproducible on: macOS 15.3 (M2 Ultra)
Not reproducible on: Windows 11

Workaround: Values are retained if the prefab remains selected when entering Play mode

Notes:
- After changing the values, sometimes they are retained, when clicking anywhere on the Inspector tab
- Removing the “DefaultSceneLoader” script fixes the issue (Game/Script)
- When clicking on Scene/Game view to unselect the prefab, behavior is inconsistent
