Enderman still doesn’t stop holding the block during death animation after dropping it, leading to visual duplication
The bug
MC-135164 was not fully fixed. It is indeed fixed for other mobs holding items, however it is not fixed for endermen holding blocks. If you kill an enderman, it still holds the block during the death animation even though the enderman just dropped it, leading to visiual duplication. Endermen hold actual blocks, not items, that’s probably why it isn’t fixed for them. Also relates to MCPE-30144.
How to reproduce:
/summon enderman ~ ~ ~ {CanPickUpLoot:1b,Health:1f,carriedBlockState:{Name:"minecraft:dirt"}}- Hit it to kill it
You still see how it holds the dirt block, even though the enderman already dropped it.
