Snowy village animal pens are guarenteed to be unable to hold animals due to waterlogged stair pond

naturally generated snow village animal pens are unable to hold any animal. whoever designed them made them 1 row too small on one side of the animal's drinking pond (the water logged 4 stairs).

I've seen a few animal pens in other villages that have only a chance of Hay Bale placement allowing for animals to eascape by climbing over them, but the water logged stair pond in snow villages isn't a chance to be too close to the fence, its a guarentee to allow for animals to climb out. please fix this oversight.
