Player (or at least the first person camera) partially slides off the bed towards the player's feet when getting in

Steps:
1) Put down bed
2) Get into bed

This is not affected by weather a block is in the way of the sliding player. Normally, when going to bed, you should be able to see your feet. But because of this, you can no longer see them.

The screenshot shows me partially slid off, with my feet no longer visible.
