The bug
When using a spawn egg on an existing mob that does not have a baby variant, a new adult mob is spawned, but without a weapon.
This happens to every mob that spawns with a weapon by default:
Skeletons
Strays
Pillagers
Vindicators
Wither Skeletons
Vexes
In 1.15.2, using a spawn egg on these mobs would not do anything at all.
