Using "/execute summon item" fails, even when immediately modified

You cannot summon a blank item: “/summon minecraft:item", but can summon a filled item: “/summon minecraft:item ~ ~ ~ {Item:{id:"minecraft:stick"}}“. So while it is expected that you cannot execute summon a blank item: “/execute summon minecraft:item run say hi“, you should be able to execute summon an item that gets filled immediately: “/execute summon minecraft:item run data merge entity @s {Item:{id:"minecraft:stick"}}“.

Steps to reproduce the issue

1. Use the execute command to summon an item and immediately modify it: /execute summon minecraft:item run data merge entity @s {Item:{id:"minecraft:stick"}}

Expected result
An item is summoned and immediately modified, in this case becoming a stick.

Actual result

The message “Modified entity data of Stick“ is sent in chat, yet the item doesn’t spawn in. The game output log says: “Tried to add entity minecraft:item but it was marked as removed already“
