PaperMC
Items moved to GUI don't drop on death
Expected behavior
There are blocks that when you interact with them, they open a GUI. When you move items into the GUI, you can exit out and those items are returned to your inventory. This includes enchanting tables, anvils, smithing tables, looms, stonecutters, etc.
Upon death while having the GUI open, the items that were in the GUI should drop. This is the behavior of the vanilla server.
Observed/Actual behavior
While having the GUI open, upon death, the items in the GUI are not dropped. They items effectively disappear.
Steps/models to reproduce
- Start a Paper server (1.21.10 build 117) with default configuration and join.
- Interact with a block (eg: enchanting table).
- Move item(s) (eg: tool and lapis lazuli) into GUI.
- Die (by any method, eg: being slain by a monster) with the GUI still open.
- Observe the items do not drop.
Plugin and Datapack List

Other
An interesting note is after death, the items are seemingly moved into the player's inventory, but when respawning the inventory is empty.
Confirmed, looks like the process for close "GUI" its called after all the death event happen causing the item being added later and ignored based in the event.
