Baby Zombie despawns taking picked-up items with it.

Behaviour: Killed by baby zombie, whihc picked up my diamond sword and armour (I know a baby got me when I was fully prepapred). Then when I respawned and returned to my death point no baby zombie in sight, but all my other dropped items were still present.

Expected: To find baby zombie in armour weilding my diamond sword. As would happen with an adult zombie.

This behaviour combined with their speed and immunity to sunlight, makes baby zombies a truely frightening mob to encounter.
