Shen E Bug

So i played shen and tried to Taunt 2 times and once, but the times i did vs he just kept chasing our jinx and used abilitys EVEN THO it showed that he was taunted and the time with i jumped onto her and she used W-Q-E-R WHILE TAUNTED and juked my Q by side steping it (i did E more than 3 times but they all worked even vs / ) Just a bug that i would like to point out.
