After sleeping in a bed, players aren't positioned in the center of a block

The bug

When standing up from a bed, the player is always positioned in the north-west corner of a block, instead of in its center.

To reproduce

1. Sleep in a bed
2. Enable F3+B
   → You'll notice that your X and Z coordinates are ending in .700 and when looking straight down, you can see that you're standing exactly in the corner of the block
