Baby villagers stuck into fences that have a pressure plate on them and bed next to them

Related to MC-147905, BTW cannot confirm

So it's only in my world? If yes why is it happening?

Please provide a video with the debug screen enabled (hit the F3 key) demonstrating the issue.

Here's the video    

Ok, now I think I have the same problem, the baby villager won't move for almost 5 minutes. To reproduce this, place a fence, then place a trapdoor on top and the bed on the side, then summon a baby villager then wait, this might take some times.

Can be recreated by placing baby villager in that house configuration and hanging out near the roof of the house above the "table." They will watch you, then jump towards you and get stuck. This will also happen naturally when they are left alone in a house, as children do. Not a big deal, as when they grow up they pop right out of there, not die.
