Trial of sekhemas - Time boss glitch - possible loss after winning

If you kill the final boss during his "twirling electricity zapping time stop landmines" attack. he continues to spin at an alarming rate for 1-3 more passes - it's not the end of the world sometimes, but i have taken honor loss after this, which means this could potentially end a run, even though he's dead, so yea, he shouldn't still be attacking when he is dead.
