[6.x] File upload drop target inconsistent when using an asset field

[robdekort]

Bug description

Screen.Recording.2025-11-25.at.15.39.22.mov

When you drag an image in the asset field stack selector the drop target are only the current folders and files, and not the whole thing. The drop visual you see when you do hit the target also suggests the whole stack should be a drop target.
