[GAMEPLAY] MALZ UNPLAYABLE - R suppression cancels without a reason

Hi, first time offender here, hoping some QA guys are actually browsing here.

Since patch 7.22 I've experienced some of Malzahar R getting canceled immediately after being cast. I'd estimate it happening 20-40% of times - QUITE A LOT, and never was there a QSS or a Mikael's on the enemy champion.

It happened in other as well games and I might have been using other runes when it happened before.

EDIT: when rewatching in slowmo it seems like the aery cancels the channel.
