[VISUAL/GAMEPLAY] Jinx ult displaying and/or not colliding correctly near death

The game i encountered this bug on was an ARAM. Jinx (me) began channeling ult, as the channel finished, Jinx died. On my screen the ult fired and went straight through Zyra who was about minigun auto distance away from the origin of the ult. Players on the enemy team saw no such ult, players on my team reacted as i did as if the ult passed through Zyra. The replay corroborates the enemy team's story as in it the ult did not fire as Jinx died before the channel completed. However the ult appeared briefly right in front of jinx's corpse before vanishing. So this is either a bug where the ult disappears if the channel finish as Jinx dies of where the ult appears to go off when it didn't.
