mentions seem to be broken

[Steve Babiak]

Mentions don't seem to be working properly using the Chrome browser on Windows.

When quoting a post, the @ does not bring up any of the thread participants except of course those named in the quote already, and @? does nothing.

And when I am trying to mention a name that is quite common among the many colleagues I have, I have to scroll to get to those near the bottom of the list (or even alphabetically beyond those names that are visible in the scrolling region) - but scrolling seems to then make that list of names go away leaving none to be selectable.

Maybe this affects other browsers and platforms as well ... please advise if you see this too.
