Items Bouncing On Lava Before Getting Destroyed

When throwing items in lava, the items will catch fire and bounce a little before getting destroyed.

 

Expected Result:

The item touches the lava and gets destroyed instantly.

 

Actual Result:

The item touches the lava and gets set on fire. Then, the item bounces off of the lava.

 

How to reproduce:

1. Create a 1 by 1 hole in the ground and place a lava source in the hole.

2. Throw a item onto the lava source. You will notice that the item lands onto the block next to the lava.
