National Irish Numbers not formatted

[kanejoe]

An example would be:

 $ieNumberStr = "059 913 1656";
    $phoneUtil = PhoneNumberUtil::getInstance();
    try {
        $ieNumberProto = $phoneUtil->parseAndKeepRawInput($ieNumberStr, "IE");
        //var_dump($ieNumberProto);
    } catch (NumberParseException $e) {
        echo $e;
    }

    echo $phoneUtil->format($ieNumberProto, PhoneNumberFormat::NATIONAL) . PHP_EOL;
    // outputs 599131656

International formatting is fine.
