The bug:
When the wither's foot is inside of any block that has a hitbox or a boat, the wither's skull would explode immediately. If there's piston pushing blocks at its foot, the skull will explode at its foot position.
How to reproduce:
method 1
build a contraption like this.
[media]summon in the wither and remove the redstone block before the wither finishes summoning.
[media][media]the wither's blue skull explodes at its foot and destroys the obsidian
[media]
method 2
build a contraption like this
[media]summon in a wither using command [to avoid the initial explosion]
[media]the wither is unable to hit the shulker because its skull explodes immediately.

can confirm this bug wither will explode a blue skull at his feet if there is a block36 or moving piston entity to be more specific kind of confusing why this happens.
minor edit: if you zero tick a block into his feet he will not shoot at his feet height.
I was unable to reproduce this in 1.17.1 the wither seemed to shoot the skulls from the heads not the bottom
Could not reproduce setup 2, and setup 1 seems WAI. Withers will break all non-bedrock blocks around them when taking damage.
