The bottom north-west corner of a Player Filter has a collidable hitbox for players

Sorry, accidentally hit enter while typing the issue.

I am not able to reproduce this issue, and looking at the code the filter has the exact same hitbox as air, torches, and other blocks without hitboxes. Is it possible that another mod in your game instance is causing this issue, or perhaps you have something like chisel and bits below the block, or you're wearing something that changes the player hitbox size?
