The expression $text of type null|string is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

		{
			$titleElement = new Html\Element();
			return $titleElement
				->init('title')
				->text($text)
				->render();
		}
		return null;
