The default CSS gives the dialog a 'left' and 'right' of zero. I think
this means that to achieve horizontal centering without actually
filling the viewport horizontally, you must set 'width' to something
other than 'auto'. Would it be useful for the width to be
shrink-to-fit if it is 'auto' and then the dialog be centered
horizontally? Or is that not a common use case?
