How to reproduce:
1. Open the attached “IN-122124.zip” project
2. Open Assets/prefabnametest
3. Switch to “Two Column Layout” mode (Project → Triple dots next to Lock → Two Column Layout)
4. Observe the Project window
Expected result: Files are consistently sorted, FBX → Prefab → FBX → Prefab → FBX
Actual result: Files are not sorted consistently, Prefab → FBX → FBX → Prefab → FBX
Reproducible with: 2023.1.0a1, 6000.0.61f1, 6000.2.10f1, 6000.3.0b8, 6000.4.0a3
Reproducible on: Windows 11 Pro (24H2)
Not reproducible on: No other environments tested
Notes:
Both views are wrong in different ways. Single column is not strictly alphabetical; Two columns doesn't respect asset type. The rule for both is: Sort everything alphabetically and resolve ties by asset type. Folders are special and sorted at the top on Windows and Optionally at the top on Mac.
