Steps to reproduce:

1. Open a Unity Project
2. In the Scene, create a new Cube via GameObject > 3D Object > Cube
3. Select the cube and check the 'Static' option near the top of the Inspector
4. Create a new material in the Project Window via Right-Click > Create > Material
5. Select the new material and check 'Emission' under Surface Inputs
6. Drag the material onto the Cube object to assign it
7. Open Light Explorer via Window > Rendering > Light Explorer
8. Navigate to the Static Emissives tab
9. Open Undo History via Edit > Undo History or the shortcut Ctrl + U
10. In the Static Emissives tab of Light Explorer, either change the Global Illumination or Colour of your material

Actual results: The change is not added to the Undo History. If you try to undo the change with Ctrl + Z then it will not undo.

Expected results: The change is added to the Undo History and you can undo it via Ctrl + Z

Reproducible with versions: 6000.0.22f1. 2022.3.48f1, 2021.3.44f1, 7000.0.0a3

Can’t test with versions: - 

Tested on (OS): Windows 10/11

Notes: 

• All other tabs in the Light Explorer add changes to the Undo History. It is only the Static Emissives tab that doesn't.
• A particular pain point is if the user changes the colour for their material. As they can't undo it, they would have to try to re-find the colour again (or open their source control to try to revert the change from there).
