Xray/Block Glitch With Ladders/Vines and Levitation Status Effect

I have recently been playing on a Minecraft server with some people, and just today have found a bug by accident. While searching the jungle for suitable house locations, I stumbled upon a rather interesting bug. I climbed a jungle tree got the the highest point of vines, held shift and kept holding W in the direction of the tree as to not fall. My intention was to get a steady vantage point but when I released shift I was climbing into the lowest leaf block. I held shift again, and I went one block higher because the base of my character was still in the vine. I have recreated this with ladders, using the same shift method, and the levitation effect while holding shift under a block and releasing. I alerted the players on the server and showed them. They were able to recreate the bug themselves, which leads me to believe it is possible on different PC's. I hope you can fix this bug, as it is fun, but annoying at times.
