That is also what causes MC-114212 to be thing. I always thought it was intended that it works like this, but appearently it is not.



Can confirm for MC 1.12.1.
Can confirm in 21w06a.
Can confirm in 1.16.5 and 21w08b.
This is because it just checks for the collision box. Because the fence/wall is 1.5 blocks high it blocks the shulker box.
Can confirm in 21w15a.
Can confirm in 1.17.
Can confirm in 1.17.1.
I am able to confirm this behavior in 21w41a. Here are some extra details regarding this problem.
