Zoey and Xayah sleep bug Free HG

During a sleep a champion is suppose to be targetable, although I realize dodges in the beginning of the ult . The sleep gives a free . I have this recorded in my highlights but am not sure how to upload them on here. Shouldn't return to the ground or be stunned in air and still be targetable once the duration of her ult time ends?
