AssetPostprocessor cannot reliably use DependsOnSourceAsset(), causing incorrect reimport of assets

Asset - Database

-

How to reproduce:
1. Open the attached TextureReImportTest.zip project
2. In the Project pane, right-click on Assets and select Reimport All

Actual: In the Console Pane, note the output that BarebonesImportConfiguration.asset has failed to load, but import continues anyway

4. In the Project pane, right-click on the Assets/Textures folder and select Reimport
5. After the import, look in the Console pane. Note that this time the output is "BarebonesImportConfiguration.asset has loaded correctly" (inconsistent behavior)
7. In the Project pane, select Assets/Configurations/BarebonesImportConfiguration.asset
8. Toggle the Default Import Settings checkbox and save. Note that the dependency is correctly detected and re-import commences
9. Toggle Default Import Settings again and save

Actual: Note that this time the dependency is NOT detected (incorrect behavior)

10. Edit the file Assets/Scripts/BreakTheTextures.cs
11. Uncomment line 10 that says "broken!" and save
12. Go back to the editor and note the script error
13. Open Task Manager and end-task Unity (simulating an editor crash)
14. Re-open the project.

Actual: Note that the textures are re-importing even though no texture settings have changed

Reproducible with: 2018.4.23f1, 2019.314f1, 2020.10b9, 2020.2.0a11
