"Links to other websites open in a new tab so that your Pinned Tab doesn't change."

Firefox version 63.0.3


Actual results:

Link is opened in a new tab, as the subdomain is incorrectly interpreted as being a different website.


Expected results:

Link should open in the same tab as the domain and subdomain are both the same website.

A subdomain can be an entirely different site. It depends on the site. :/

To everybody finding this issue, it might be possible to suppress the behavior by using <base target="_self">
