When importing an asset, you can't deselect a partially selected folder.

Godot version

System information

Godot v4.1.2.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3060 Laptop GPU (NVIDIA; 31.0.15.3141) - 11th Gen Intel(R) Core(TM) i7-11375H @ 3.30GHz (8 Threads)

Issue description

When importing an asset, a file selection window line this appears:

You can select individual files or whole folders, and when a folder has some of its items selected but not all, it appears like this:

Clicking on this checkbox will select all of the items in the folder, then clicking it again will deselect all of the items in the folder. This is working as intended. However, if some of the files can't be imported, due to file type, conflict, being gdignored, whatever, clicking this button does nothing. It feels like a good idea to me that instead it should deselect all files, if the only files not selected can't be selected.

Steps to reproduce

1. Open a project
2. Go to AssetLib and hit import
3. Select a zip file
4. Find a folder with some unselectable files
5. Try to deselect the parent folder

Minimal reproduction project

Open an empty godot project and attempt to import this zip:
SignalUtilities.zip
then try to deselect the .godot folder or the editor folder inside of .godot.

I think this was already reported somewhere because that's just how the intermediate mode works in Trees. It is annoying though.
