[Gameplay] Kallista Autoattacking Through Fiddlestick's Fear

So I was in game today, playing as Fiddlesticks. There was a Kallista in bot lane, and I homeguard out to engage her. She throws here Q at me and jumps towards me, and as she does so I fear her. The little fear icon appears over her head, but she CONTINUED AUTO-ATTACKING ME. At first I was confused, thinking I had feared a minion by accident, but I asked her and she confirmed she was indeed feared yet continuing to auto-attack me. Needless to say, I died. This is a severe gameplay bug, especially if it applies to other champions' cc on Kallista.

Thanks,

Swuft

P.S. Happened in Normal 5v5 Summoners Rift
