VI Ult is bugged

I haven't noticed this until recently but VI ult is bugged with J4 and Tristana and possibly more interactions.

If VI ults a J4 with his standard Dash her ult completes where J4 was before dashing and J4 completes his dash putting him out of range of VI. J4 Bug in action

With Tristana Her ult can knock Vi back while VI is ulting her putting that distance between VI and tristana when VI's ult finishes

Master Yi's alpha strike is also completely negating her ult and putting it on full cooldown
