Affects Version/s: Minecraft 16w50a, Minecraft 1.11.2, Minecraft 17w06a
Fix Version/s: None
Likely caused by the most recent fix of
1. Place a brewing stand
2. Place a stack of empty glass bottles somewhere in your hotbar
3. Right-click the brewing stand
4. Shift-click the stack of empty glass bottles
5. Observe the stack move into the main inventory. Expected: One glass bottle moves into the brewing stand, the rest of the stack remains where it is. See enchantment table for this (correct) behavior.
