I do not think Gabriel knew what Issei was doing. Remember during the sports festival between the Devil, Angels, and Fallen Angels. First I think Azazel tried to go after her in an ecchi manner, and Issei tried to use Dress Break on her. It said that she was clueless about the fact the Issei was a pervert. And maybe neither she nor Michael knew that he had seen through her clothes in the first place.
