Lighting is not applied correctly after using Progressive Lightmapper when Scene Reload is disabled in Project Settings



How to reproduce:
1. Open User's attached "Unity 2019.3 Bug" project
2. Load "SampleScene" (Assets -> Scenes)
3. "Generate Lighting" ( in Lighting Settings)
4. Ensure that "Reload Scene" is disabled in Project Settings -> Editor
5. Enter the Play mode
6. Observe the paint cans and workbench

Expected result: paint cans, lamp and workbench are correctly lit
Actual result: paint cans, lamp and workbench are not correctly lit

Reproduced in: HDRP 7.0.1, HDRP 7.1.1 (2019.3.0b5, 2020.1.0a6)
Not reproduced in: HDRP 5.2.3PV (2019.3.0a2), HDRP 6.5.2PV and HDRP 6.9.1PV (2019.3.0a9), HDRP 7.0.0 (2019.3.0a11)
Can't reproduce in: 2017.4.32f1 (no HDRP), 2018.4.10f1, 2019.2.7f2, 2019.3.0a1 (no "Scene Reload" setting in Project Settings)

Notes: the best way to observe the difference between "correctly and incorrectly lit" Game Objects is to take one screenshot of Play mode with "Scene Reload" disabled and one with "Scene Reload" enabled

Workaround: enabling "Scene Reload" in Project Settings -> Editor

- The issue happens only in the Editor and doesn't happen in the Standalone player.

    This seems to apply to URP as well.
