Godot version

v4.0.alpha.calinou.f0407ad14

System information

Linux, Nvidia 1650GTi, Vulkan

Issue description

Here is an example open dialogue:

There is a directory missing from here, Source. It's not showing up. Any directory with project.godot inside it does not show up; typing the directory name will still take you there.

Steps to reproduce

Try to import/edit a project. May happen with other related (non-res://) dialogues.

Minimal reproduction project

N/A

This is not a bug, project.godot denotes another project and they are ignored on purpose. (they also don't show in filesystem dock)
If dialogs weren't like that before, likely #46638 changed it.

(This is https://codeberg.org/unfa/Liblast liblast; it contains the project file in a directory called Game, that is not visible here.)

I assume that it is intended for if the projects are already listed in the project manager. That was not the case here - these projects were not listed there and the directories were not showing.

[KoBeWi]

Ah if it happens in Project Manager then it's a bug. The folders are supposed to be filtered only in editor.

CC @ev1lbl0w - we seem to be a bit too thorough in the results we filter out, as indeed folders with project.godot need to be visible for the "Import" / "Scan" dialogs in the Project Manager.
