Pointed dripstone affects villager pathfinding

While attempting to build a village in a Dripstone Cave, I noticed the villagers frequently have trouble navigating around or over pointed dripstone. The problem doesn't always occur, but occasionally I will find a villager stuck in a random location in the cave because he's trying to walk through pointed dripstone but doesn't seem to be able to move away once he's touching it. This happens with all lengths of the stalagmites. They don't seem to always acknowledge it as an obstacle and don't attempt to avoid it sometimes. They will sometimes become stuck in one spot, unable to return to their beds at night.
