anchor element stopped using target=_blank

On commit fbc3f2893a3fa9177a73af15c36beb46eaa2707c of git.pleroma.social/pleroma/pleroma, I observe the following:

Previously <a> elements in the profile (for example https://social.n0.is/users/1) and any other <a> in the pleroma-fe would open links in new tabs.

Now this changed (for logged-in users) to open links in the same tab, no target=_blank. This has been verified with Firefox 63.0.1 as logged in user. I was not able to reproduce this with Torbrowser 8.0.2 (FF 60.2.1esr), here links work as expected (open in new tab).
