This is unfortunately not supported. The Form container supports one flag per
field (where fields are defined by the form's sections). Form has no way of
knowing that you have multiple text inputs inside the box pane, so it can't
attach a flag to those text inputs. It can only show a flag for the fields it
knows about.
