The bug

If a warden gets angry at a piglin or piglin brute, and said piglin transforms into a zombified piglin before the warden can kill it, the warden will not remain angry at this zombified piglin and will need to become aggressive toward it a second time.

How to reproduce

1. Summon a warden in the Overworld or End
2. Summon a piglin or piglin brute nearby
3. Have the warden get angry at the piglin before zombification

Expected results

The warden would remain angry even when the targeted piglin becomes a zombified piglin.

Actual results

It loses its target.
