Title: Avoid popup flickering on new suggestions

This fixes the popup flickering in a simple way -- we do not hide an existing popup window when we go to get new suggestions from the server. This ensures that:

1. The old popup should remain for the duration of the RPC call, and
2. The popup will automatically be cleared and updated once that RPC call has returned.
