Kalista Autoattack-move Bug

There is a bug with the change to Kalista's auto attack canceling that will sometime not allow her to jump between autoattacks and can be a major problem while trying to kite champions and teamfight positioning. The auto canceling fix that allows her to change targets will sometimes mistake a click away from enemies as a target change (I'm speculating) and will not allow her to jump to the cursor for that click.
