1.10.2 Cladding Duplication bug (using offhand)

[brisingraerowing]

If you have a stack of, say, 48 cladding, use some (e.g. to get it to 32), and then switch the stack to the offhand, then the stack size will suddenly be 48 again, this can be done at any stack size, and basically gives infinite cladding for one block.

I haven't tried with other blocks added by this mod, so I don't know if this happens with them as well.
