TP interrupted by khazix bug

I was playing a game against a khazix, and during a teamfight i was teleporting in Jarvan's spear not a ward or minion. The khazix then got to disable my tp with one of his skills. I'm not sure what; I don't think khazix has any cc that would have disrupted my tp. I asked the player after game and he said he used his w, but he also doesn't think it should have been interrupted.

Ofcourse this might have been a misclick on my part but the timing of his skill when it hit me and disrupting me is just too much of a coincidence. I hope riot will look into this.
