How to reproduce:
1. Open the project “IN-113668_LightTesting”
2. Open the “SampleScene.unity” scene (Project tab → Assets → Scenes)
3. Open the Search window for lightmaps (Examples → SearchProvider → Show lights)
4. In the Search window, on the left, select Project → QueryLightmaps
5. Observe the “Lighting Data Asset” column
6. Generate Lighting and wait for it to finish (Window → Rendering → Lighting → Generate Lighting)
7. Observe the “Lighting Data Asset” column in the Search window from step 3

Expected result: Each lightmap’s lighting data asset remains set to “LightingData”
Actual result: Each lightmap’s lighting data asset is “Missing (Lighting Data Asset)”

Reproducible with: 2023.1.0a1, 6000.0.57f1, 6000.2.3f1, 6000.3.0b1

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Notes:

• The project is based on the following documentation: Unity - Scripting API: SearchProvider. The documentation is for Unity 6.0, however it is exactly the same to any supported stream documentation for 6.2
• The provider with the Search Column is defined in Assets/LightingProvider.cs
