End portal and end gateway falling block entities and moving piston blocks are invisible

Run the following commands:

/summon minecraft:tnt ~ ~ ~ {block_state:{Name:"minecraft:end_portal"}}
/summon minecraft:minecart ~ ~ ~ {CustomDisplayTile:1b,DisplayState:{Name:"minecraft:end_portal"}}
/summon minecraft:enderman ~ ~ ~ {NoAI:1,carriedBlockState:{Name:"end_portal"}}
/summon falling_block ~ ~2 ~ {BlockState:{Name:"minecraft:end_portal"},Time:1b}

The first three correctly generate entities which render as end portals, however the last one, despite correctly carrying end portal block data (as can be seen when it lands), is completely invisible. This is incorrect behaviour; the falling block entity should be as visible as the other three.

It is extremely likely that moving_piston blocks with end_portal or end_gateway data experience the same issue, however due to the fact that pistons cannot move these blocks, as well as the continued existence of MC-129017, this cannot be confirmed without modifying the game.
