Honey blocks do not prevent fall damage like in Java but just makes you take the full grunt of the fall.

Hi Ghostcat,
The behaviour according to the release notes indicate "Greatly reduces movement speed and jump height, but also reduces fall damage", not that it negates fall damage completely. Source
I've just done some testing and, from a fall of roughly 14 blocks (with no armour or enchantments) onto a solid surface I took 6 and a half hearts of damage. The same fall onto honey and I took 3. This would seem to indicate its working as intended but as you said "full grunt" can you elaborate at all on your experience?
