A way to disable items from dropping from GUI's

Issue description

Could we have a way to disable items from dropping from GUI slots.

I made a tutorial on trading mechanics but someone brought to may attention that the mechanics that I used drop both the trade item and the currency item if the currency slot has the item in it, it gets added to the inventory when it should only drop the emerald. Video tutorial: https://youtu.be/0_eqw9VAl3I?t=238

If we where to disable the dropping we could do the following.

Test for the item which we want to only drop or add to the player's inventory
use the spawn gem or directly add the item to the players inventory.

Thanks in advance :D

Disabling dropping for specific slots would be even better, although I am not 100% sure if possible :D

I could do this but it will only work in cases where GUI is not bound to the entity/item/block. This means it is still OK for the trader GUIs which do not need binding but are only opened without any inventory link.

This would be supper, at the moment I don't see a high demand on adding support for linked GUIs, however, it still may be a long term goal to allow players the option to disable if they want to. But if there is no demand yet I don't see the need to to work on it :)

This feature will be added in 2020.4. Closing the ticket :)

You specify this per slot
