auto-sliding on some blocks

The game makes me slide automatically to an edge (like there was water on it) when I'm on a Soul Sand block, Farmland block, or Grass Path block.

I don't know if other blocks are affected by this bug, I tested only a few (different kinds of dirt and blocks with a heigh of less than one block), but I suppose I'm not the only one to report this bug since these are pretty common blocks.
