Entity shadow is not rendered in some cases where it is expected to be

To reproduce

Enter a superflat world
Place any solid block
Summon an entity over that block
/give @p creeper_spawn_egg{EntityTag:{NoAI:1b}}
Its shadow wont be visible from ground level
If u stand on a trapdoor the shadow would be z-fighting
