Beetroot unknown to Villager AI

I found a Village with beetroot. (One of the new 1.9 items.)
The farmer villager was farming crops, but the Beetroot froze the AI, Cause a cycle of attempts to harvest and fails.

The farmer Villager AI of what I know, is to harvest crops and replant seeds.

The farmer Villager AI was staring at the Grown Beetroot, turns attention to another villager, turns back to beetroot. Repeats over and over.

To Reproduce:
1. Find a Village with Beetroots in one of the farm beds.
2. Watch as a farmer villager is confused.
3. (Optional) Laugh at the villager.
