[Gameplay] Mordekaiser Suppressed if Sett Ult's Him during animation

Playing Mordekaiser as I ult'd Taliyah, I was ult'd by Sett the same time and the moment I entered my realm I was suppressed for about 6 seconds.

I don't have anyone to test with me to see if this happens every time but hopefully the youtube video I linked to can describe the bug better than I can.
