Villagers claiming workstations too far away

I have villagers in minecarts for easier trading with a workstation behind them. I noticed that some of the villagers have claimed workstations too far away and wont refresh trades. I do not if this is intended or not.

Easiest way to reproduce:
1. trap some villagers in minecarts
2. place workstations behind them
3. brake workstation to see which villagers claimed it
4. some will have claimed workstations too far away and not the one behind them.
