Lulu Glitterlance locks out Kayle R

I was just in an aram game and got traded Kayle. When I'd try and ult myself my R would be locked out if Lulu hit me with Glitterlance. I was also unable to cast it on team mates when this happened.

Now before anyone comments about poly being used these were occasions when she'd already poly'd someone else so that wasn't the issue.
