### 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
_move_operation_confirm(p_path, move_dialog->is_copy_pressed());
}
void FileSystemDock::_move_operation_confirm(const String &p_to_path, bool p_copy, Overwrite p_overwrite) {
	if (p_overwrite == OVERWRITE_UNDECIDED) {
		to_move_path = p_to_path;
		to_move_or_copy = p_copy;
		Vector<String> conflicting_items = _check_existing();
		if (!conflicting_items.is_empty()) {
			
			overwrite_dialog_header->set_text(vformat(
					TTR("The following files or folders conflict with items in the target location '%s':"), to_move_path));
			overwrite_dialog_file_list->set_text(String("\n").join(conflicting_items));
			overwrite_dialog_footer->set_text(
					p_copy ? TTR("Do you wish to overwrite them or rename the copied files?")
						   : TTR("Do you wish to overwrite them or rename the moved files?"));
			overwrite_dialog->popup_centered();
			return;
