Prefab Editing Environment does not use default volume settings resulting in all white scene when editing prefab
How to reproduce:
1. Open user-submitted project (HDRPPrefabTest.zip)
2. Open the EditScene - see that the PostProcess Volume exposure is disabled
3. Open the SampleScene and select the Cube Prefab, click 'Open'(in 2020.1 and 2020.2 it should be opened from the Project window)
Expected result: the Prefab Environment looks identical to EditScene
Actual result: the Prefab Environment is all rendered white
Reproducible with: 2019.4.0f1(HDRP 7.4.1), 2020.1.0b12(HDRP 9.0.0 - preview.13), 2020.2.0a14(HDRP 9.0.0 - preview.13)
Not reproducible with: 2018.4.24f1(HDRP 4.1.0 - preview)
Could not test with: 2019.3.0b12(HDRP 7.1.5) - disabling exposure renders the EditScene all white, so it's impossible to tell if the Editing Environment works or not

Resolution Note:
After investigation of the setup and how the code is supposed to work I concluded that this was working as designed.
The point of the prefab isolation mode is to be completely isolated from the scene editing environment as such, we can't incorporate the default settings in there because they are part of the "main stage" so they can't be in both the main stage and the prefab isolation stage (Volumes are just regular game objects so we can't make an exception for them when editing a prefab).
If a prefab environment scene is designed with very high intensity lights and sky then it's expected that a corresponding exposure setup is made.
