Villagers attempt to pathfind under trapdoors despite their hitbox being too large

Villagers will attempt to walk under trapdoors despite their hitbox being too large, causing them to get stuck walking against a trapdoor despite there being other paths they could take.

To replicate this you could build something like I have shown below. When they want to go inside they'll often get stuck on the trapdoors under the roof. They will not stop trying to walk under the trapdoors until I open them.

EDIT: this also happens with trapdoors on the ground and two trapdoors layered ontop of eachother, with one being on the cieling and one being on the ground.
