Lightmap baking fails when URP Template content is put into a subscene

Repro steps:

1. Check out latest 2022.2/staging (tested with git commit 62ca96eb270df00114e34114a5155944030c179f)
2. Check out latest DOTS master (tested with git commit c15f5229c91b3e0d202461b8ea1870159b59d9ee)
3. Extract the attached test project into a sibling folder of the DOTS checkout
   • E.g. if DOTS is in C:\UnitySrc\dots, the test project should be in C:\UnitySrc\EntitiesLightmappingBug, so the relative package path works
4. Open the scene Assets/Scenes/SampleScene.unity
5. It's the default URP template, but with the assets moved into a DOTS subscene
6. Click Window > Rendering > Lighting > Generate Lighting
7. GI baking goes into an error loop, repeatedly giving this error message:

   Integrate failed on Write Lighting Data job.
   

• • The editor becomes unresponsive due to the error loop

 

Expected behavior: GI gets regenerated, and Entities get updated with the new lightmaps

Actual behavior: GI baking repeatedly fails with an error
