Search box nickname completion is fun

[blattersturm]

If searching from: a specific user, say, jack#3333, you can enter from:jac in the search box, and if they recently sent a message, they'll show up right away for you to click or press down->enter on. However, if unlucky, a deferred member list search may complete at the same time, and you accidentally end up completing to jackie#0420, then if really unlucky having no way to retrieve the last user you've tried to search without entering their full name and discriminator.

This is especially fun if their message got deleted since, or they have a username full of Unicode special-cases.
