When the player sneaks over cake that is suspended over a fall of more than a block, the player will fall off of the cake easily as if they were not sneaking at all to remain on the block.

Steps to reproduce:

-Make a one block pillar from the ground surface.

-Place a cake on top of the pillar.

-Sneak on top of the cake towards the edge of the block.

-The player will fall off of the cake and the block it was placed upon.
