Steps to reproduce

1. Make a 3x2 room with solid block walls except for fences across one of the 3-wide sides. Give the room a roof at the 4th block up so that you cannot walk from the bed onto the fence. (See screenshot and video.)
2. Place a bed on one side the room so that its head is opposite the fence.
3. Spawn a villager in the room and then push it against the fence at the foot of the bed.
4. Set time to night.
5. Set time to day.

Expected result

The villager wakes up on the bed or next to the bed, inside the room.

Observed result

The villager wakes up inside the fence and walks through it out of the room. (If this does not happen then rebuild the room with the fence side on the north as in the video, and try again.)

I made a market in Minecraft as one does and placed the villagers in their respective rooms with their respective work objects and beds but after sleeping, they often escape the (still closed) room somehow and change work objects, like they don't want that lectern anymore. It's become quite annoying, please help.
