### Issue description

Trying to move a folder results in moving error and it's not moved.
Regression from #75330

A fix already exists, but I'm opening an issue so it's not lost (the PR isn't ready and not very active).

### Steps to reproduce

1. Add 2 folders in filesystem
2. Move one folder into another one

### Minimal reproduction project

N/A

		return nullptr;
	}
	if (DirAccess::exists(p_path)) {
		
		return nullptr;
	}
	const String type = ResourceLoader::get_resource_type(p_path);
	Control *tooltip = EditorResourceTooltipPlugin::make_default_tooltip(p_path);
	for (const Ref<EditorResourceTooltipPlugin> &plugin : tooltip_plugins) {
		if (plugin->handles(type)) {
			tooltip = plugin->make_tooltip_for_path(p_path, EditorResourcePreview::get_singleton()->get_preview_metadata(p_path), tooltip);
		}
	}
	return tooltip;
}
Variant FileSystemDock::get_drag_data_fw(const Point2 &p_point, Control *p_from) {

	Vector<String> paths;
