Cloning brewing stands doesn't copy the "BrewTime" NBT value

The bug

When cloning furnaces that are in the middle of smelting, CookTime block data is copied from the source blocks to the destination blocks and the furnaces finish smelting at the same time. However, cloning brewing stands does not operate the same way. The copied brewing stand resets and must start brewing from the beginning, so the two brewing stands end up finishing at different times.

How to reproduce

Fill brewing stand; half way progress bar, copy it with CTRL + Middle Mouse Click, or use /clone
→ The progress bar (BrewTime) is not saved, and it resets
