[GAMEPLAY] Draven autoattack while death with GA

While playing a game recently we had the most astounding bug occur. Draven was caught by 3 people and went all in. He was killed but had a guardian angel. While the death animation was playing an axe that he had thrown landed on his dead body. While still lying dead on the ground, he throw the axe killing one of our players and triggering his gold passive showering his dead body (which was still laying prone on the ground), about a half second later his GA restored him to health to where he flashed but was not able to get away. Everyone including the person was playing Draven was very confused. I don't think he clicked for the attack, but rather it reset the internal counter such that the next scheduled autoattack for nearest target was triggered.

It appears there is some odd condition in which a landing axe can refresh his autoattack even when he is untargetable and invulnerable while in GA. The axe and his death were very closely spaced in time so there may have been a race condition for a short time window.
