TLD for domain test.ru is not recognized about tldextract

[layershifter]

There is no issue with the package, test.ru and others are marked as reserved in the ICANN section of Public Suffix List: https://github.com/publicsuffix/list/blob/6f2b9e75eaf65bb75da83677655a59110088ebc5/public_suffix_list.dat#L5884

So, even Extract::MODE_ALLOW_ICANN will not help you there, php-domain-parser has a same issue there because it uses the same database. However, test.ru should be suffix in this case.

Wouldn't this be fixed by changing the code here (line 225-227 of Extract.php)

        if ($suffix === $hostname) {
            return [null, $hostname, null];
        }

to this:

        if ($suffix === $hostname) {
            return [null, null, $hostname];
        }

?

Is there a reason the suffix is being placed in the "hostname" when there's just a suffix?

You can still work around it, I suppose, since the TLDDatabase library is a dependency, you can just use that pacakge to check if the string is a public suffix first.
