For some reason, my mentions aren't quite working right. When I type the @ symbol, the majority of the time the pick list for the mentions does not open up. It looks like the pick list doesn't open for me whenever the @ is typed on the first line (basically before any line break).
As an example, here is what it ends up looking like:
A few of my users are reporting that the pick list opens, but closes after one character being typed.
I am using Chrome x64 (latest). NodeBB is up at 1.4.1. No errors in the Chrome console either.
Edit: And of course, after typing this, I also see the issue with the pick list closing after typing one character.
