armor stands are not dropped as part of their loot table / loses custom data when broken

Armor Stands do not keep data when destroyed. Normal procedure if I understand things correctly is to create a custom loot table for any custom data that is to be preserved. But, the loot table for armor stands does not include the armor stand itself and is always created regardless of loot tabe, so there is no addressable destination for copy_custom_data, except adding a new item to carry the information.

While this allows for kludge workarounds, expected behavior would be like that of block entities which drop themselves together with ejecting their contents, very much like armor stands do, except hardcoded.
