I accidentally posted in the wrong project and then I posted in what I thought was the correct ticket and there was asked to create a new ticket. I have just tested and verified that this also occurs in 1.15 Pre-Release 2.

Description: I was testing an issue that I had with the last snapshot where some villagers would not go to bed at night. I teleported to a snow village and instantly watched a villager die by suffocation, it's head was in the ceiling above or near the bed. You can see this in the screenshot I've attached. I've also included a fresh copy of the world (named Pre-Release1 Pre-Release2VillagerTest.zip) created with seed # 7333969029456169764. I have "cheats" enabled so you can quickly type in "/tp -502 70 -643" or "/tp -507 70 -642" to get to the point in the screenshot.

To reproduce:

1. When creating a new world with seed # 7333969029456169764 click "enabled cheats" then "create world" (or use attached saved file)
2. type "/tp -502 70 -643" when you spawn in the world

You will then fall down to the coordinates exactly at the screenshot point and see a villager standing on a bed with its head through the wall suffocating.
