### 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
Dictionary drag_data = p_data;
	if (drag_data.has("favorite")) {
		if (String(drag_data["favorite"]) != "all") {
			return false;
		}
		
		TreeItem *ti = tree->get_item_at_position(p_point);
		if (!ti) {
			return false;
		}
		int drop_section = tree->get_drop_section_at_position(p_point);
		TreeItem *favorites_item = tree->get_root()->get_first_child();
		TreeItem *resources_item = favorites_item->get_next();
		if (ti == favorites_item) {
			return (drop_section == 1); 
		}
		if (ti->get_parent() && favorites_item == ti->get_parent()) {
			return true; 
		}
		if (ti == resources_item) {
			return (drop_section == -1); 
		}
		return false;
	}
