Camera goes up when flying or getting close to lava while a solid block is beside the player character

In this bug report I want to mention a bug with the camera when standing near lava.

Steps to reproduce:

1. Go to a flowing down block of lava
2. Make sure that there is a solid block next to you (left or right)
3. Go in first person view
4. then switch to third person view and back to first person
5. you should see the camera going up and the bug confirmed

Expected results:

Camera should not go up when standing near lava while a solid block is next to you!

Observed Results:

The camera moves up when standing near lava and there is a solid block aside the player character.
