If in block when you log out, you spawn 1 block lower

If you logout with a block in you (works best with enchantment table), you will lower 1 block into the ground!

Doesn't effect non-solid blocks you can walk through, and most solid blocks. Worked for Enchantment Table, End Portal Frame, Beacon, Lit Redstone Ore, Well, pretty much any block solid.

Steps to reproduce:
1. /setblock ~ ~ ~ stone
2. Restart world
3. Fall through block
