Summary: Completion dropdown sometimes causes NPE

Initial Comment:
A completion dropdown can get into a state where the completions dropdown is empty but still visible.  Clicking the empty dropdown causes an NPE on the event-handling thread.

Compile and run the attached test case.  Type a, a, <del>, <del>, <del>, o.  You should end up with an empty dropdown.  Click on it, and you'll see the NPE on the console.
