Grass path blocks and tilled dirt push you off

This issue wasn't present in pre-release 4 and only popped up with pre-release 5. If I am standing on either a grass path block or tilled dirt block (any block that is 15/16 blocks tall) that is adjacent to a block with a lower Y-value, my character is seemingly being pushed off the block as if there is a water flow or another entity pushing me.
