I'm trying to show a KONtx.control.Header in a fullscreen view, but the background doesn't extend all the way accross the view. It looks reasonable in fullscreen unless the header is centered or right-justified. I noticed that there is a textStyles property to control the label, is there another style I should be using to control the width of the background image? I've tried this:

var foo = new KONtx.control.Header({ ... styles: { width : Theme.viewSpecs.FULL_SCREEN.width, ... }, textStyles: { width: Theme.viewSpecs.FULL_SCREEN.width, ... }
