Center of double chest has a gap in its hitbox

The Bug

When creating a double chest, there is a missing bit of the hitbox, allowing players to hit through chests.

To Reproduce:

1. Create a Double Chest at least 1 block above ground
2. Create another Double chest below it
3. Put contents in the second Double Chest
4. Aim your crosshair in the middle and attempt to open the Double chest

→ The Double chest below gets opened.

Original Description

i wasnt gonna report this because it wasnt that much of a problem...but i kept hitting the middle of the chest and nothing happens...no opening of the chest or anything, except that you can hit things and mine things behind the chest persay a cobblestone block.
