This is a different bug, not a duplicate, I shall add the setup I had made

This was the setup of where i found it

It is still a dupe of MC-2334 as it has stated 'sneaking on shorter than full blocks will make you fall nonetheless'. Carpet is 1/16 blocks high, so it is still considered a not full of a block, making you fall.

The actual issue is not sneaking on shorter-than-full blocks, but sneaking anywhere there is a drop of less than one whole block. So since a carpet is 1/16 of a block, the drop is only 15/16 of a whole block distance.

I think that Minecraft considers any block that is not full 'safe' to fall, as you still can build if you fall. I don't know if this is right though.
