Gameplay - Malzahar's ultimate being canceled

In general, Malzahar's ultimate gets canceled if for example Renekton used his W stun, you use your ultimate before the basic attack lands but your ultimate as Malzahar will still get canceled even if Renekton is suppressed because he hit/almost hit you before the ulti started. Its similar to the old Volibear bug where if you flashed the second Volibear Q'ed you, you would still get flinged all the way back even if you flash away. Similar situations happens with other champions. you for example cast Echo's Q and it is mid animation when you are suddenly suppressed, the Q will still cast. In short Malzahar's suppress won't stop abilities which are almost done with their animation.
