[GAMEPLAY] Dead Syndra still gives vision

Occasionally, on death Syndra's body will still give vision to a wide area around her. It happens for all deaths for the rest of the game, and it is definitely just her body giving vision, not any hidden wards or anything like that. I managed to find another video of someone documenting the bug here: https://www.youtube.com/watch?v=tvQuF_K_YM0 .... figured I would submit it as well in case it offered any clues as to why this happens.

Apologies if this bug has already been submitted. I thought more people would be talking about it by now, but it happened again in our clash matches last night. I can provide video of the entire match where it happened if it will help.
