We just launched a new site with a pretty short domain name (www.wwf.ch) and realised, that all internal links where opened in a new window.
When debugging I realised that the pattern for the external link detection is not really reliable. I made a js fiddle to demo a few cases with the regular expression from the current dev extlink.js:
https://jsfiddle.net/yqmgbbd0/6/
I copied the results here:
www.example.com => sub: www.example. , host: example.com
www.example.com:8080 => sub: www.example. , host: example.com
www.example.co.uk => sub: www.example.co. , host: co.uk
test.example.com => sub: test.example. , host: example.com
example.com => sub: example. , host: example.com
As you can see the subdomain and hostname are not reliable detected. As domain detection is pretty complicated i would recommend to use something like https://github.com/wrangr/psl.
On the other hand a workaround for the bug is relatively easy, as it is possible to set a internal domain name in the module config.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
@Neslee Canil Pinto maybe we could mark as fixed and continue over at 🐛 not working for subdomain like http://www.xyx.com/my-en Active
