[GAMEPLAY] Tower completely ignoring Kayle for a good 8 seconds of diving

Turret completely ignores Kayle who's consistently dealing damage to Rumble inside of turret range for a good 8 seconds. Completely gamebreaking. I haven't seen anything like it before, and I haven't tried to reproduce it either. I suspect that it has to do with very precise timing of Kayle ultimate and drawing tower aggro.

EDIT: Turret ignores a target that has kayle ultimate before they trigger turret aggro. The turret then proceeds to ignore the target after the ultimate has ended until it has finished the minion it is currently attacking. Seems unintended?
