Ghost items can be created using /item (server doesn't update client inventory correctly)

      Using /item to replace the item in a player's hotbar slot frequently creates ghost items. Right-clicking with a ghost item will still place a block, but it does not show up in the hotbar.

      This did not happen in 1.16.5.

      Steps to reproduce

      1. Set up a repeating command block with the following command: 
        item replace entity @p hotbar.0 with dirt
      2. Drop the dirt block
        → The slot will become empty, even though the /item command should refill it
      3. Press Q again while selecting the first slot
        → You'll drop dirt, even though there's no dirt in that slot
      4. Right-click onto a block while selecting the first slot
        → A dirt block gets placed
