Description

Expected behavior

When a zombified piglin is agro'd to the player and killed by the wither it should drop a wither rose.

Observed/Actual behavior

When a zombified piglin is agro'd by the player and is killed by a wither, it fails to drop a wither rose.

Steps/models to reproduce
  1. Cage a wither
  2. Spawn zombified piglins in the cage
  3. Agro the zombified piglin
  4. Make the wither target the player so it starts hurting the agro'd zombified piglins
  5. Wait until the zombified piglins have been killed by the wither
Plugin and Datapack List

None

Research direction

Start by reproducing the issue with the listed wither, zombified piglin, and player-aggression steps on Paper 1.21.8-25. Compare the result with a piglin aggravated by an iron golem; done means an aggravated zombified piglin drops a wither rose when killed by the wither, without plugins or datapacks.
