Extended piston hitboxes do not include their arms

The Bug:

When a piston is extended, its arm isn't included within its hitbox. Please note that this report is talking about extended piston hitboxes and not piston head hitboxes.

Steps to Reproduce:

  1. Place down a piston and activate it.

  2. Look at the hitbox of the extended piston.

  3. Take note as to whether or not extended piston hitboxes include their arms.

Observed Behavior:

There is no hitbox of the arms of extended pistons.

Expected Behavior:

A hitbox would be present on the arms of extended pistons.

MC-4504 also mentioned pistons, but only in the description; brewing stands were indeed fixed.

Confirmed for 1.13.1.

On bedrock edition that part of the piston is a full block hitbox instead. MCPE-83258

Can confirm in 1.18.1. I'd like to request ownership of this ticket if that's alright since I believe the current reporter's account has been deactivated. 🙂

Affects 1.18.2-pre3; I've opened MC-248786 to cover the core issue responsible for this problem.

Can confirm in 1.20.6
