Username with dots are not clickable
Summary
When you tag/mention someone using @
, you expect the mention to convert into a link when rendered. Unfortunately this is not the case when the username has a dot (.
) in it. I am also not sure whether an email mention is generated when these users are tagged/mentioned.
Steps to reproduce
Let's tag Peter Thomassen (@peter.thomassen) and this is his profile url
Expected behavior
@peter.thomassen should be clickable
Actual behavior
It is not clickable
