Exactly MCPE-58715 but for items instead of experience orbs.

When a mob is killed, the dropped items now spawn directly at the bottom center of the mob, all in the exact same place with only downward velocity. Items therefore do not spread out unless they spawn in midair.

Expected behavior is for them to spread out in random directions similar to block drops.

How to reproduce
Set up a repeating command block followed by a chain command block:

summon cow ~ ~0.5 ~
kill @e[type=cow]

Power it for a few seconds and observe the drops – all in the exact same place.
