Falling blocks can land on blocks they're not supposed to

Credit to _MethodZz_ for finding this bug.

The bug

When a falling block slides over a fence or cobblestone wall, it can land on blocks it is not supposed to.

Steps to reproduce

  1. Build the setup in

[media]
  1. Place a sand block under the observer
    → Notice the sand will land on top of the torch

Furthermore, if there is no torch, the sand will just drop as an item.
