When I was working with an enchanting table, holding shift for sneak, it still makes you fall off the block if you go to its edge.

I was expecting that when I hold shift and go to the edge of the block that I would not fall off the block unless I jumped.

What actually happened, was when I was on the enchanting table, and I was holding shift, I fell off the block once I got to the edge of it.

To reproduce the bug, place down an enchanting table in creative or survival, make sure that you are not flying, and get on the block holding shift. Then go to the edge of the block and you will fall off.
