Third person camera cannot move through barriers

Same as MC-189617.

Since the block is invisible, the camera should treat it as such.

Also inconsistent with the behaviour of other invisible blocks.

Steps to reproduce:

1. Place the barrier.
2. Change the view to a third person view.
3. Try to walk the camera through the barrier.

Observed results:
The barrier blocks the camera from a third person.

Expected results:
The camera will not be blocked by barriers.
