I expected when trying to do a 20 * 20 * 20 cube of glass to have it not calculate 20^3, but it actually used 20^3.
How to reproduce:
Do a hollow /fill on a cube that has more blocks than 4096 (eg. 10 * 10 * 10)
You would expect it to not show (8000 > 4096) but the number of blocks on a hollow 10 * 10 * 10 cube.
Please don't put down the affected version as a future version, as you don't have access to it yet!
