Bug Description

Hi

i started locally a new server based on the latest Paper version, appended the plugins WorldEdit and WorldGuard and nothing more.
I execute the command /stack ingame to stack a.e. shulker boxes. In my inventory the shulker boxes (minecraft:shulker_box) are now stacked.
If i move the stacked item into a chest (minecraft:chest) as example, the stack will be unstacked. Same issue if i throw the stack to another player.

Expected Behavior

The stack of the items shouldn't be unstacked, if i move it into a chest (same as in earlier version - don't know the earlier version exactly).

Reproduction Steps

1. Download PaperMC for Minecraft Version 1.21.1 and start new server (eula,...)
2. Download WorldEdit
3. Download WorldGuard
4. Start server
5. Register as OP
6. Ingame get some shulker boxes (via gamemode creative) and execute command /stack
7. Set a chest ingame and move the stacked shulker boxes into the chest
