Regression

Yes

Prefab's thumbnail gets reverted to one without reflection when reimporting asset after initializing EditorUtility.SetDirty()

-

How to reproduce:
1. Open the user's attached project "My project.zip"
2. Open the "GetPreview" window from "Tools" > "Get Preview..."
3. Drag and drop the "Sphere" prefab from the Assets folder to the Object Field
4. Press "SetDirty", observe the prefab's thumbnail
5. Press "Reimport", observe the prefab's thumbnail

Expected result: The prefab's updated thumbnail is saved after reimport
Actual result: The prefab's thumbnail gets reverted to one without reflection

Reproducible with: 2020.2.4f1, 2020.2.7f1, 2020.3.32f1, 2021.2.17f1, 2022.1.0b14, 2022.2.0a9
Not reproducible with: 2019.4.37f1
Could not test with: 2020.1.0a1, 2020.1.0a26, 2020.2.0a1, 2020.2.3f1 ("Sphere" GameObject does not reflect the skybox in Scene/Game View)

Notes:
- Also reproducible by pressing “SetDirty” and then selecting the prefab
- 2022.1 "GetPreiview" window's preview image shrinks after pressing "SetDirty"
- 2022.2 "GetPreiview" window's preview image shrinks and does not get reflection updated

    The prefab thumbnail don't have reflection since unity 2018, setting it dirty will show the correct thumbnail until the prefab is re-imported right away. (Setting dirty is just for demonstration)
