Scene is brighter in Standalone player if it was open in the Editor at build time

Affects Version

-

Reproduction steps:

1. Check out repository https://github.com/Wilfrid-Unity/test-unity-scene-brightness that contains repro-projects
2. Start UnityEditor from Trunk revision 38ec60822087 or later (Oct. 17)
3. Open either project "test-birp-scene-brightness" or "test-urp-scene-brightness" (issues happens both in URP, BiRP, and HybridRP)
4. Make sure that scene "Scenes/BlocksScene" is NOT opened in the Editor
5. Build and run a first Development Build of the project that includes only scene "Scenes/BlocksScene"
6. Take a first screenshot of the scene in the first Standalone Player
7. Now in UnityEditor OPEN scene "Scenes/BlocksScene"
8. Build and run a second Development Build of the project that includes only scene "Scenes/BlocksScene"
9. Take a second screenshot of the scene in the first Standalone Player

Expected Result: First screenshot and second screenshot look the same.
Actual Result: First screenshot is darker, second screenshot is darker. Regression introduced in Version 2019.4.20f1;

- The same issue happens in both Windows Standalone Player, as well as Switch Standalone Player (I did not test other platforms)

    I can see differences in the way environmental lighting is handled between editor and build regardless of what scene is open at build URP. It seems related, so a fix would be welcome.
