Game crashes when trying to save after modifying item stack to have a max_stack_size below its current stack size

When modifying an item stack to have a maximum stack size below its current stack size the game crashes the next time it tries to save.

How to reproduce:

1. Give yourself a stack of stone (/give @s minecraft:stone 64) and select it in your hotbar.
2. Modify the max_stack_size component to 32:
/item modify entity @s weapon {function:set_components, components: {"minecraft:max_stack_size":32}}
3. ❌ Notice the chat message: "Can't deliver chat message, check server logs: Replaced a slot on <playername> with [Stone]". The game logs are attached
4. Pause the game to cause it to save.
5. ❌ The game crashes. The crash log is attached.

Note that when you split up the stack between steps 3 and 4 to be below the new max_stack_size, the crash does not happen and the stacks do have the new max_stack_size.
