Issue description

using FileDialog with FILE_MODE_OPEN_ANY mode, print selected files. If I select a file first, then select a dir in the same dir, then click Open, this editor return the path of the file, not the dir.

After checking the code, I think this is because when I select a file, FileDialog::_tree_selected set select file name into file

void FileDialog::_tree_selected() {
	TreeItem *ti = tree->get_selected();
	if (!ti) {
		return;
	}
	Dictionary d = ti->get_metadata(0);

	if (!d["dir"]) {
		file->set_text(d["name"]);
	} else if (mode == FILE_MODE_OPEN_DIR) {
		set_ok_button_text(ETR("Select This Folder"));
	}

	get_ok_button()->set_disabled(_is_open_should_be_disabled());
}

then in FileDialog::_action_pressed, file->get_text() return a exist file, cause select dir is ignored.

void FileDialog::_action_pressed() {
	if (mode == FILE_MODE_OPEN_FILES) {
		TreeItem *ti = tree->get_next_selected(nullptr);
		String fbase = dir_access->get_current_dir();

		Vector<String> files;
		while (ti) {
			files.push_back(fbase.path_join(ti->get_text(0)));
			ti = tree->get_next_selected(ti);
		}

		if (files.size()) {
			emit_signal(SNAME("files_selected"), files);
			hide();
		}

		return;
	}

	String file_text = file->get_text();
	String f = file_text.is_absolute_path() ? file_text : dir_access->get_current_dir().path_join(file_text);

	if ((mode == FILE_MODE_OPEN_ANY || mode == FILE_MODE_OPEN_FILE) && (dir_access->file_exists(f) || dir_access->is_bundle(f))) {
		emit_signal(SNAME("file_selected"), f);
		hide();
	} else if (mode == FILE_MODE_OPEN_ANY || mode == FILE_MODE_OPEN_DIR) {
		String path = dir_access->get_current_dir();

		path = path.replace("\\", "/");
		TreeItem *item = tree->get_selected();
		if (item) {
			Dictionary d = item->get_metadata(0);
			if (d["dir"] && d["name"] != "..") {
				path = path.path_join(d["name"]);
			}
		}

		emit_signal(SNAME("dir_selected"), path);
		hide();
	}
//...
}
