I thought that this had never been shown to happen with closed containers. I always thought that this was an issue of open containers allowing for evaporation and hence a smaller amount of frozen water, and that if lids were put on then the cold froze faster.

Does anyone have any thoughts on the vague explanation proposed in this link?
