Villager get stuck in Diagonal placed blocks

Villagers get stuck in Diagonal place blocks, which are on the height of their head (they can't jump over them)
 
What I expected to happen was...:
When they were searching for their beds or running away from Zombies, I expected them to get inside the houses that were really near.
 
What actually happened was...:
Instead, they would go in the right direction but would get stuck in corners like these (see screenshot)
 
Steps to Reproduce:
1. Find a village
2. Place Blocks like in the screenshot/ find Blocks already placed like this.
3. Wait till it gets night/ place down some zombies so they are triggered to get into their houses in the shortest way possible.
 
Screenshot:
The arrow shows where they wanted to go.
The red circle shows where they got stuck.
