{# Which profile's defaults the control is showing, so start_scan can apply
   the submitted profile's defaults when a submit lands before the control
   followed a profile change.  The page renders a reserved value naming no
   profile until the lazy list load answers; it is re-rendered out of band
   only in the swap that replaces the control's defaults, never before.
   autocomplete is off so form restore cannot bring back a value the server
   did not render. #}
