 // Other platforms don't appear to have the sense of "key window" that
 // Mac does (I believe their fields lose focus when the window loses
 // focus).  Rather than modifying focus outside the control's edit
 // scope, when the window resigns key the autocomplete popup is
 // closed.  model() still believes it has focus, and the popup will
 // be regenerated on the user's next edit.  That seems to match how
 // things work on other platforms.
