In order to theme certificate viewer html dialog with a different style on
chromeos, we need to promote bubble_window_style to more general dialog_style.
This way, DialogStyle can be used as a parameter for function ShowHTMLDialog.
However, only chromeos builds will use this parameter, others just ignore it.
