Landing on top of Honey Blocks doesn't reduce fall damage

Description/Introduction

In the Minecraft Wiki, it says: "Like with Haybales, landing on top of Honey Blocks will reduce fall damage by 80%". However, as I was messing around with fall damage reducing blocks, I noticed that the fall damage reduction didn't work, and I died from a height that was survivable using haybales.

 

Expected results

Receiving the same amount of damage as with the haybales; 7 damage points/3.5 hearts

 

Observed results

Normal fall damage applied, killing the player (me)

 

Steps to reproduce

1. Place a Honey Block down

2. Go up to a height that would kill you if landing on any other block

3. Land on top of the honey block
