While exploring a cave I came across a natural lava spring. While walking onto a stone block directly adjacent to the flowing lava my character seems to levitate up about half a block. While floating I am able to jump and clip slightly through the ceiling (3 blocks high) and see through the ceiling (similar to an x-ray mod). I have included a short video demonstration.

This is on an Xbox One S, playing on a REALM server using version 1.14.1
