Picking up arrows in the second hand and an item makes the item invisible

Summary:
If a player picks up an item and arrows and has arrows in their off hand, a desync may occur and the item will become invisible, with the wrong amount (if there was already a stackable item in the inventory) and unmovable until re-entering the world or before any interaction.

Steps to reproduce:

1. Take 1 arrow in the off hand.

2. Throw away the arrow.

3. Throw away more items.

4. Wait a couple of seconds.

5. Approach the thrown items.

6. Open your inventory and look at the items.
   Throw arrows first, then items! Throw in one place without moving the screen.

Observed results:
The item picked up with arrows became invisible in the inventory.

Expected results:
Items will not become invisible.
