Jinx's E blocking Zac even if he flies over it!

Hi guys! I've noticed a bug regarding Zac's E (Elasting Slingshot) and Jinx's E (Flame Chompers!).

When Zac casts the E from the distance, even if he crosses over Flame Chompers while in the air, he gets blocked by them. The point is that:

1. He shouldn't get blocked cause he is still in the air and not phisically OVER Flame Chompers;
2. While Zac is in the air one random trap explodes and blockes him when he reaches the floor.

Let me explain you that with some "easy" paints (all the screenshots were black after pasting them on Paint >.< ): http://oi62.tinypic.com/6f8uq0.jpg

I add that I've tested this in a custom game versus a Jinx so I'm not lying, try it!
