Occasionally, when teleporting yourself using a commandBlock, you will become stuck in your destination block. It looks like the client is trying to fall into the block, but the server is telling it not to. It's comparable to a fixed bug where mining with an Efficiency V tool would occasionally fail to remove the block, but it would not appear for the client. The only solution is to either relog, or to enter creative mode and fly up.

What I expected to happen was...:
To be teleported on top of the block.

What actually happened was...:
I was teleported slightly inside the block, and thus unable to move out of it.

Steps to Reproduce:
1. Teleport to a destination using a commandBlock.
2. Occasionally, you will be stuck in the block.
