[BUG] clicking an equippable item in the hotbar has the player kicked for 230 bytes extra whilst reading packet 13

Prerequisites

• [X] I made sure I am running the latest development build
• [X] I tried to look for similar issues before opening a new one
• [X] I have set debugmessages=true in config to diagnose my issue
• [X] I have redacted session tokens and passwords before attaching screenshots

Minecraft Version

1.20.2

Console Client Version

260

Expected Behavior

/inventory 0 click 37 RightClick with an armor in the 2nd hotbar slot and an empty armor slot should equip the armor.

Actual Behavior

/inventory 0 click 37 RightClick with an armor in the 2nd hotbar slot and an empty armor slot gets the player kicked for sending a bad (oversized) packet.

Left clicking a sword actually causes the same error, but it's 265 bytes extra instead of 230.

Clicking an empty slot actually does no harm.

Steps to Reproduce the bug

1. Connect to a server (survival mode).
2. Have an armor or a sword in the hotbar.
3. In case of the armor have an empty armor slot.
4. Right click the armor or left click the sword via /inventory 0 click <slotnumber> <RightClick|LeftClick>
5. Get kicked.

I have the same question，when i open the inventory list ，I notice that the name of the item is not same as the real game，and when i try to use the inventory to choose the server menu to choose a game, I was kicked by the server.

When using the menu, if you are kicked out of the server for the click solt command, you can try using drop as a replacement, which will not result in you being kicked out of the server.
