Villagers won't select or stay with brewing stands that are on top of blocks as their work station.

I believe this happens unless you put it on the ground. The only time I can get a villager to take to a brewing stand is if it is on the floor.
Now I come to think of it, I think it is related to or actually caused by this bug MC-156126
I have experienced this too, it seems they are less likely to remember a brewing stand if it is placed atop another block instead of standing on the ground. They often forget their jobsite untilt the brewing stand is broken and placed again.
Other jobsite blocks and their corresponding villagers seems to be fine with a workstation placed one block up from the ground except with the brewing stand.
