Renaming a stack of previously unstackable items behaves unexpectedly

Renaming a stack of 64 beds for example will destroy the anvil, drain a single experience level for each bed and destroying the anvil.

**To Reproduce**
Steps to reproduce the behavior:
1. Set beds to be stackable to 64
2. Give yourself atleast 64 levels and an anvil
3. Switch to survival and rename the stack of beds to anything
4. Witness a horrifically loud sound that simultaneously breaks the anvil and drains you of all your levels

**Expected behavior**
It should use just one singular level and not demolish the anvil

**Version:**
- Minecraft Version: [1.20.1]
- Mod Version [v2.0.0]
- Java Version [1.17]

**Additional context**
Ow my ears

Start by reproducing the issue in Minecraft 1.20.1 with AllStackable v2.0.0: make beds stackable to 64, then rename the stack in survival using an anvil. Trace the stack-renaming and anvil interaction, and consider the fix complete when renaming the stack consumes one level, preserves the anvil, and does not produce repeated break sounds.
