Player momentum perpendicular to an edge is not cancelled when sneaking up to said edge

When sneaking up to an edge, the players momentum is not cancelled in the direction perpendicular to the edge, as it would be the case for walls. This is especially noticable on ice, where you need to sneak for multiple seconds before letting go without falling off the edge.
