Standing on tilled farmland next to water makes you get pushed into the water no matter the blocks around the farmland or how many blocks there are near the farmland. It can be 1, it can be 3, it still pushes the player into the water, even if the water block is waterlogged. Example in the attachments. This started happening in pre-release 5.
Edit: It also pushes the player to the side where there's no farmland if there's no water.
