When an item is thrown on top of certain blocks such as honey or soul sand, it will abruptly lose all of it's velocity and fall straight towards the ground in an unexpected manner.

Steps to Reproduce:

1. Create a strip of honey or soul sand on the ground (~3-5 blocks long)
2. Aim the camera near 0.0, 0.0
3. Throw an item along the strip of blocks
   → observe result
4. Throw an item on a ground made of a different block
   → observe result

Observed Behavior:

On the honey and soul sand, the block will stop mid-air and fall straight to the ground roughly 1-2 blocks away from the player.

Expected Result:

The item would either not be slowed yet because it is not actually on top of the block when thrown (and thus should not take it's properties), OR it would have it's velocity slowed down smoothly, rather than instantaneously.
