I doubt you can do anything about the form itself as this form comes directly from QG. Maybe some js to sent css classes/properties it then someone may say you are tampering the form as the whole idea of using it is to put your cart outside the pa-dss scope.
I'll give them another day to response and then I will post it as a bug in 4.4.1. I hope for some intelligent answer or explanation from QT
