Describe the issue

When you are in thrid person with Leawind's Third Person, you should see nothing through the portal, no block, nothing. But if you come closer, you see that you actually see a few tens of block above what is on the other side of the portal. Also it seems that the chunk of the other side of the portal is visually cut. But if you look in first person everything is fine (obviously), and if you go in the portal in third person you end up at the correct height, so it's purely a visual bug.
