[MC-240862] wither is immune to all undead(except withers)

i went into a creative world a spawned a wither then started spawning undead mobs around it and watched the undead aggro then repeatedly fail to hurt the wither

i tested zombies, baby zombies, drowned, baby drowned, zombie villagers, wither skeletons, skeletons, zoglins and zombified hoglins

i also summoned another wither with it in a small box and they could hurt each other

how to replicate

set difficulty to hard
spawn a wither
spawn any undead monster
wait for the wither to hit the other mobs with a random skull
watch them try to hurt it and fail

This ticket is invalid as it contains multiple issues. Many of these are already being tracked and are currently in progress: MC-162633, MC-177878, MC-184330.

its one issue all the mobs listed are undead

Please consider reopening this ticket as it encompasses several others. The issue affects all undead mobs collectively, making it unnecessary to keep multiple tickets open for individual undead category mobs. Consolidating them into this single ticket would streamline the resolution process.

Can confirm in 1.21.3 and 24w46a

Except it would actually hinder that... It may be entirely by design some of the mobs are intended, while others were accidental. Having them all in 1 ticket would prevent properly giving each case their resolution.

I don't think any specific undead mobs should damage the Wither, because the Wither is completely immune to damage from any undead and it's definitely WAI. These senseless attempts to cause damage create a non-productive behavior
