X-ray gltich 1.11

I put a rail down and a minecart on it. Then ,i put a leaf on the minecart and hopped into minecart.

What I expected to happen was to see darkness or the texture of the leaf

What actually happened was that i became able to see throught the blocks and see caves and stuff from the minecart.
