Champ disappears off screen for a few seconds

I was fighting Storm on master. I swiped back and when I did my champ was almost gone off the screen which effectively blinded me. She used her sp3 and I was able to dodge it but it's was only luck and I was surprised I actually dodged it. I have a video of it and it happens around the 1:02 mark.
