Hi blackhawk and welcome to the forums!
Maybe I'm misunderstanding, but wouldn't this just be "Undo"? If Undo doesn't work I think the only option you'll have left is to recreate the style manually. If you're looking for the default style from InfoPath, you could delete the control and add it back to the form.
