Even drag crafting does not work

Even drag crafting (Holding in mouse3 and dragging it on the crafting table so it puts an even amount of every item in each slot you dragged it on) does not work. It looks like it puts 64 items in each slot but it really isn't there. Thank you for resolving this bug that has been here since the start of the 1.8 snapshots

*What I expected to happen was... there would be an even amount of items in the crafting table slots

*What actually happened was... it didn't work and it looked like it had a stack of items there.
