Quick Open gets stuck after hitting ESC then quickly opening it again

[njx]

Only tried on Mac.

1. In a JS file, type Cmd-T - Quick Open bar appears
2. In quick succession, hit Esc, then Cmd-T again

Result: Most of the time, the Quick Open bar appears again but doesn't have focus, and you can't get rid of it. Esc doesn't close it, and neither does clicking in it and then focusing out. Bringing up Quick Open again opens a second bar (and a third, and a fourth...)

High priority to me. Probably yet another focus race condition that is exacerbated/exposed by the animation that we added.

Opening to Sprint 31.

Fixed, closing.
