When wither skull hit mobs no projectile damage

The expected design is to cause 8 (4 hearts) projectile damage when the wither skull directly hits the mobs, when hitting a entity or block, it will rupture and cause an explosion, with a power of 1 and a maximum damage of 15 (7.5 hearts). In normal and difficult difficulty, directly hitting a mob will cause a level 2 wither effect of 10 seconds and 40 seconds, respectively, and the damage value received by the player will be adjusted accordingly according to the difficulty.

In the current situation, the wither skull only causes explosion damage and wither effects, no projectile damage.

When players are repeatedly killed by the skull fired by the Wither, the result will only be "exploded by the Wither". If they die from the wither Effect, it will be "withered". There has never been a direct hit causing "killed by the Wither" or "shot by the head fired by the Wither".
