When i double tapped a single loose dirt block in my inventory to become a stack, all the remaining blocks in my inventory does not merge together.
How To Reproduce:-
Step 1:- Have a inventory full of one block only in all slots.
Step 2:- Double tap a block to stack them together.
The block does not get stacked together.
When double tapped a single block, all the same blocks in the inventory should stack up together.
Hoping this information is helpful to fix the bug.
