The hitbox of walls that made a pillar is too large, when it is connected to the side.

How to reproduce:

1. Place 2 walls next to each other.
2. Place a torch or lantern on top of one of the walls to form a piller
3. Look at the wall to see the hitbox

Observed Results
The hitbox is above the wall to the sides of the pillar

Expected results
The hitbox will only be around the pillar and the visible top of the wall

Before 1.16 it also used to be too high when it doesn’t have a pillar, which is now fixed, but, when it has a pillar, it is still incorrect.
