Description

Expected behavior

(Singleplayer Behavior)

When an item is being picked up in your inventory, and the inventory closes, the item will go into the hotbar, and play an animation while doing so.

Observed/Actual behavior

On singleplayer this works fine but on servers this doesn't play at all.

Steps/models to reproduce

Plugin and Datapack List

None

Paper version

This server is running Paper version git-Paper-362 (MC: 1.19.3) (Implementing API version 1.19.3-R0.1-SNAPSHOT) (Git: 52718db)
You are running the latest version
Previous version: git-Paper-360 (MC: 1.19.3)

Other

This isn't really specific to paper servers but rather any server. But it should be a good thing to fix regardless.

Research direction

Start by reproducing the linked video scenario: pick up an item in singleplayer and on a server, close the inventory, and compare whether the item enters the hotbar with its animation. Trace the inventory-close and hotbar-transfer behavior in the server/client interaction; done means the animation plays consistently on servers as it does in singleplayer.
