[1.21] Jade Compat breaks when adding a void upgrade to Ender Drawer

[Real-Septicake]

It seems that getSlots() was used in the Ender Drawer portion of the compat code instead of the intended getStoredStacks().size(), resulting in an IndexOutOfBoundsException when applying a void upgrade

Functional Storage Version: 1.3.6

Titanium Version: 4.0.28

Error Log: (The internal calls are cut for brevity)

Not just Jade, applying Void Upgrade also breaks drawers themselves. Item quantity limits are gone, and UI also shows no items inside, or any upgrades.
