Closing a trapdoor on feet bug

The Bug

Closing a trapdoor on your feet while sneaking, then un-pressing sneak, makes your camera be lower in first person then on the outside. Hope that the steps to reproduce clarify this bug better.

Steps to reproduce:

1. Place down a trapdoor in the open position on the ground
2. Sneak, and keep holding sneak until instructed not to in these steps, and close the trapdoor so that it is lying on the ground and not sticking up
3. Stop holding shift
   → In 3rd person, you are normally standing
   → In 1st person your camera is lowered into what it would look like if sneaking
