Lava or water being held by an enderman isn't rendered, even though their arms are extended

The bug

Lava and water are not rendered at all in the hands of endermen, even though their arms are extended as if they were holding something.

How to reproduce

1. Run the command:

   /summon minecraft:enderman ~ ~ ~ {NoAI:1,carriedBlockState:{Name:"water"}}

1. Run the command:

   /summon minecraft:enderman ~ ~ ~ {NoAI:1,carriedBlockState:{Name:"lava"}}

1. Notice that both endermen do not render their carried blocks.
