Rabbits have trouble path-finding when on a half most most part of a stair, on the side of a block, under an upper slab.

Rabbits, cute, fluffy sometimes VERY invasive made into Minecraft in version 1.8 and they have some bugs.

Rabbits have problems with path-finding with the side of blocks, the half most part of stairs and upper slabs, Seen by these screenshots below.

Now I haven't check If the bug is present in older versions, if somebody can find if the bug is present in older versions, that would be good.
