I was just exploring in spectator in the new snapshot, when I stumbled across this scene (see image) Apologies if this has already been reported, I didn't see anything on it.

Edit: I could not find the one i originally posted an image of, however i found a similar example in the same world, and will be attaching a picture of that, in addition to the coordinates and seed
