Bows being weird

Basically, whenever I shoot a bow in the new 14w07a snapshot, the arrow seems to hit an invisible wall and does the animation for hitting walls.

What I expected to happen was the usual stuff- the bow would shoot, and hit the target (a Baby Zombie)

I shot the bow and the arrow seemed to hit a wall and fall down, though the target was still damaged.
Steps to Reproduce:
1. Take a bow. (This was in creative, not sure what happens in survival)
2. Pull it back, same as normal.
3. Shoot it.
