code: @Override
      protected void onLoad() {
  	super.onLoad();
  
  	// these styles need to be the same for the box and shadow so
  	// that we can measure properly
  	matchStyles("display");
  	matchStyles("fontSize");
  	matchStyles("fontFamily");
  	matchStyles("fontWeight");
  	matchStyles("lineHeight");
  	matchStyles("paddingTop");
  	matchStyles("paddingRight");
  	matchStyles("paddingBottom");
  	matchStyles("paddingLeft");
  
  	adjustSize();
      }
docs: Matches the styles and adjusts the size. This needs to be
  called after the input is added to the DOM, so we do it in
  onLoad.
