Third person camera cannot move through barriers

Although the third-person camera can move through certain transparent blocks like glass, tall grass, or iron bars, it acts as if the most transparent block of them all, the barrier, is a fully opaque block that the player cannot see through.

To reproduce

1. Build a wall of barriers
2. Stand in front of it
3. Enable third-person camera (F5)
   → Notice that the camera is placed just on the wall and cannot move behind it
