Villager are attacked by husks but they don't run away from them

in minecraft 1.10 (every version) the villager are attacked by husks but they don't run away from them. also if you try to get the egg from the husk (by middle mous button or k) it gives you the normal zombie egg.

i expected the villager to run away from the zombie, but the villager just stood there.

1 spawn a villager
2 spawn a husk a view blocks away from the villager
3 observe what happens
