Master Yi + Guinsoo's Rage BUG

I just played a game as Master Yi and bought guinsoo's rageblade and frozen mallet. When guinsoo had 8 rage stacks, guinsoo's rage was activated triggering bonus on hit effects.

BUT while guinsoos rage was active, i kept attacking myself and due to frozen mallet slowed myself too. You can test this by buying guinsoo on Master Yi and do the rift scuttler. Normally you shouldn't loose any health, but you will. Alternatively try it with frozen mallet or randuins omen, you will be slowed.

Please fix this bug.
