The Bug

When attempting to make a snow golem, dispensers can incorrectly place carved pumpkins up to two blocks away from snow blocks in the North, West, and Down directions of the world.

Steps to Reproduce:

This issue cannot be easily replicated in it's entirity, instead, these steps will be a simple reproduction of one of the possible incorrect placements

1. Give the player a dispenser with carved pumpkins in it:

    /give @p dispenser{display:{Name:'{"text":"MC-137248","bold":true}'},BlockEntityTag:{Items:[{Slot:0b,id:"minecraft:carved_pumpkin",Count:64b}]}} 1

2. Replicate the following setup shown here:
   

Observed Results:

The dispenser is able to place the pumpkin in a place where it will not produce a snow golen.

Expected Results:

The dispenser should only place a carved pumpkin where it would actually produce a living snow golem.

Notes:

Using the /fill command repeatedly, I have tested every possible location where the carved pumpkin can be placed, and have come up with this:

1. The structure:
   dispenser_pumpkin_placements.nbt
2. The orange stained glass is where carved pumpkins can be placed.
3. The lime green glass is where the carved pumpkins should be able to be placed.
