According to the Minecraft Wiki, wandering traders can close and open wooden doors, not iron doors. However, they can open them like they're made of wood. It surprises me that a mob can actually open the most unopenable door in the game. How can this be?
Steps to Reproduce
Build a small house with an Iron door and a fenced area.
Set time to Day
Spawn a Wandering Trader
Set time to Night
Spawn a zombie type of mob or illager in the area.
The Wandering Trader will use its Invisibility potion
What I expected: It will stay over that area since it can't open the Iron Door.
What actually happened: It managed to open the Iron door and go inside the house.
