Light in prefab reverts to realtime after moving the prefab with light to additively loaded scene and entering Play mode
Steps to repro:
1. Open the attached project and "SampleScene" scene;
2. Drag and drop scene "1" from the Project folder to Hierarchy to load it additively;
3. In the Hierarchy drag Directional Light (1) prefab from scene SampleScene to scene 1;
4. Parent it to MainCamera gameobject in scene "1" (in one go);
5. Enter playmode;
6. Exit playmode;
7. Rotate the Directional Light (1) gameobject;
Expected result:
Light is baked and doesn't update in the Scene or Game view when rotating it.
Actual result:
Light is realtime and is updating in the Scene and Game view windows.
See the attached video.
Notes:
- Reproducible in Version 2022.2.0a15, 2021.3.3f1;
- Reproducible on Windows.

Latest issues
- Rendering/Decal Layer Mask options are different inside Prefab Mode and outside Prefab Mode when the project is upgraded to Unity 6
- The Shortcuts window cannot be docked when it is invoked from the Shortcut Helper Bar
- Incorrect Realtime GI Light Probes baking when more than one Light Probe Group is used and "Baked Global Illumination" is enabled
- Hovering on the three-dot menu also highlights the tab header near it when not all tabs fit the bar
- Crash on PPtr<Object>::operator when undoing "Modern UI Pack" elements
Resolution Note:
The lighting data is bound to the scene and lights are registered with the scene they are baked in. When you move a light to another scene it will no longer be patched correctly when the scene is loaded. Playmode goes trough a loading sequence so it will not work.
Notice if you move the light back to the scene it was baked with it will work fine again.
