The TLD .com.ru is handled incorrectly

[hkopp]

Hi,
I have encountered a bug when handling .com.ru domains.

In [1]: import tldextract

In [2]: tldextract.extract('http://lamy.com.ru/')
Out[2]: ExtractResult(subdomain='lamy', domain='com', suffix='ru')

I would have expected the following:

Out[2]: ExtractResult(subdomain='', domain='lamy', suffix='com.ru')

.com.ru is in the list of public suffixes, so this is clearly a bug: https://publicsuffix.org/list/public_suffix_list.dat

Thanks for creating the library by the way. I first tried sed with increasingly complex regular expressions, but that quickly grew out of hand. Your library was exactly what I needed.

And my version number:

In [5]: tldextract.__version__
Out[5]: '3.3.1'

And troubleshooting of the cache:

(venv) $ pwd
/home/user/.cache/python-tldextract
(venv) $ ls
3.10.5.final__venv__699cb6__tldextract-3.3.1
3.10.6.final__venv__699cb6__tldextract-3.3.1
(venv) $ cat */publicsuffix.org-tlds/*.tldextract.json| jq '.'| grep ".com.ru"
    "com.ru",
    "com.ru",

Thanks for the thorough diagnostic info! That suffix is pretty far down the list, so it's in the private domains section. See the FAQ.
