Right-clicking on unemployed villagers sometimes cause hand animation to stop after a villager has a profession

The bug

When right-clicking onto an unemployed villager before that villager gets a profession, hand animation stops.

How to reproduce

1. Spawn a villager (Automatically unemployed)
2. Right-click on the unemployed villager
   → As intended, the unemployed villager shakes their head and grunts.
3. Place a workstation block
   → Right-clicking on the villager that now has a profession, shows the trade UI, but the hand animation has stopped working.
