[GAMEPLAY] Backing animation kept playing even after back was cancelled.

Had a bug in my most recent game on Wukong where I channeled my back, but it was cancelled from ignite that was on me. I hit b right after it cancelled(I thought I did at least) and Underworld Wukong's back animation started, audio and all, but I never actually went back when the channel time was up.

Now, it's possible I never actually hit b again to start the back channel again, HOWEVER the animation and sound did start up again or at least kept going after the ignite tick.

Not sure how to attach the download of the replay. The game is Wukong Ranked flex on 3/17/2017 I went 4/8/1 with 159 cs. The bug can be reproduced in the replay. It happens at 2:24, and if you hit the rewind 15 seconds button at 2:38, you'll see exactly what I saw in game, but without the back channel bar I was watching from my shop.
