Reflecting Ghast Fireballs is nearly impossible

When trying to deflect a Ghast Fireball, is is almost impossible, differing from previous versions, in which is was very easy to do so.

What I expected, when trying to hit the fireball, was for it to fly back up at the angle I hit it.

Instead, almost always, the fireball will most likely a) Phase through the punch/hit or b) Explode on contact with the punch/hit.

Steps To Reproduce:

1. Get a Ghast to fire at the player.
2. Try and hit the fireball with a single punch/hit. You will find this is hard, and that the player must spam-click to even have a chance at hitting it, and, even still, it will probably explode anyway.

This is a serious issue, as being unable to deflect the fireballs can result in damage and burning of structures, as well as player death.
