Issue 1:
When a player tries to hop onto a block with 1.5b free space above him while sneaking, the plugin prevents them in most cases and sometimes sends the Passable check message. They will eventually succeed in getting up but it can take quite a few attempts.
Issue 2: When the player stands on a shulker box and there are two blocks or less between the box and the roof, opening the box will trigger lots of Passable violations while the player is standing on it.
How to reproduce the issue
Issue 1: Set a single block on the ground and build a roof with slabs so that between the block and the roof, there are 1.5 free blocks. Go into sneak mode and try to jump on that block.
Issue 2: Put a shulker on the ground and three blocks above the shulker a block. Step onto the shulker and open it.
