Miss Fortune Double Up indicator attaches to minion [Gameplay]

When you are playing Miss fortune and (without quick-cast) click Double Up and hover the indicator on a minion, you see an indicator to show where the second shot will go. However, once you've use the ability, if you hover your mouse over the skill icon, you'll see the indicator appear on the unit you previously clicked, even if that unit is dead.

Note: I don't own MF, so I've only observed this on ARAM.
