F5 camera zooms in to avoid kelp

When swimming through the oceans (absolutely beautiful, by the way) in F5 mode, so the player model can be seen from behind, the camera zooms all the way in to the player when he/she swims through kelp, like when the view of a player is obstructed by a wall. While this could be considered as not a bug, the zooming in breaks the immersion of swimming through the ocean. It would be far better if the camera remained steady.
