When you have 1-63 empty bottles in your inventory, 1 water bottle in your main hand, and you right click an empty cauldron, the new empty bottle is still in my main hand, not stacked with the other bottles in my inventory. This problem also occurs with filling honey bottles, which are stackable. For example, with 3 honey bottles in my inventory, and 1 empty bottle in my main hand, after right clicking a bee nest with honey_level:5, my main hand now holds 1 honey bottle instead of stacking it with the other 3 already in my inventory. Is this an intentional feature? If not, please fix this.
