Quick Open does not find any text files (.txt, .md) unless a text file has already been opened in the Script Editor this session

Tested versions

tested in v4.6.3.stable.official [7d41c59c4]

System information

Godot v4.6.3.stable - Windows 11

Issue description

On opening a project, searching for text files (.txt, .md) using Quick Open doesn't find anything, and those files have to be opened from the FileSystem dock instead.

However, after opening any text file from the FileSystem dock, Quick Open seems to start finding all the project's text files.

Reloading the project doesn't seem to reset this, but fully restarting Godot does.

---

Instead, I would expect to be able to Quick Open all of these files without loading one with the FileSystem dock first.

Steps to reproduce

• open the MRP
• use Scene -> Quick Open (in my testing, this doesn't show any of the text files from res:// in the search results)

• open one of the text files in the Script Editor using the FileSystem dock
• use Scene -> Quick Open again (in my testing, this now shows our text files)

Text files aren't Resources, so technically quick open shouldn't be able to see them. The script editor uses an internal TextFile resource as a hack to open text files.

Text files aren't Resources, so technically quick open shouldn't be able to see them.

That's a fair assessment of the current technical background. But from a user side I'd argue that quick open should be able to open stuff that's supported in the text editor.

The editor needs to shift away from this "everything relevant is a resource" paradigm. (Since the GDScript longterm goal most certainly is, to drop the "script is a resource" thing).
