Bees deal no damage if difficulty is set to peaceful

The bug

If the difficulty is set to peaceful, hostile bees will try to attack the player, but deal no damage.

To reproduce

1. Summon a bee or multiple bees
2. Change the difficulty to peaceful
3. Attack a bee
   → The bee will try to attack you, but won't succeed

The same happens if steps 2 and 3 are switched.
