Basically the title.

If the player is on a grass path block that's next to a non-solid block (not diagonally), the player will be pushed off the grass path block.

This seems to affect no other entities. Just the player.

(upon checking the issue list, this seems to affect all blocks like the grass path (grass path, farmland, soul sand). Blocks like slabs and snow don't seem to be affected by this bug)
