The idea is that when the SelectAreaFrame (which is the parent) of the options
is asked to paint then it asks the ListControlframe to paint the focus ring in
the correct spot. It need to find the first non-disabled option (ignoring opt
groups) and if nothing is selected it need to find the first frame which is the
dummy option. Also, it now track thru a static data member which listControl
frame currently has focus (this was taking from how comboboxes track it internally)
