Some items which can be used to place the respective entity in the world do not apply the custom item name to the entity. This means once you destroy the entity and pick it up as item it will not have a custom name anymore.

- armor stand
- firework_rocket (keeps data as an item though? as if dropped onto the floor)
- fishing_bobber (from fishing rod)
