Lulu Polymorph and Buffs - Visual bug in client and in spectator mode

Lulu's Polymorph can cause a visual bug, appearing as though a champion has 2 Red Buffs, one remains for the entirety of the game.

1. Select Ezreal on red side and Lulu and any third champion on blue side.
2. Have the third champion obtain a Red Buff.
3. Have Ezreal kill the champion with Red buff, transferring it to him.
4. As step 3 occurs, have Lulu cast Polymorph on Ezreal.

Note: The video shows this occurring in the first 12 seconds, ignore the rest. Note: This occured with Ezreal's Q- Mystic Shot in the video. Note: This is ONLY a visual issue, as one instance of the Red Buff will disappear normally and be transferred normally, one is stuck on Ezreal for the entirety of the game.
