Crouch+Left Click Dragging to evenly distribute items in crafting grid stops functioning correctly from the second stack onward

[nite]

The first stack even distributes through the crafting grid, as shown in this picture

but when you try to distribute another stack on top of the existing one in the grid, weird things happen. this one was distributed starting from the top left and moving clockwise, and it appears to leave all of its distribution that would be intended for the last space in the 2nd space it passes over instead

this is consistently true (though i think at different + larger stack sizes it does weirder things), and if you click and drag from other starting blocks the same thing happens

when a third or higher stack is dragged, shit starts getting really weird. dont think i could figure out the pattern for this one, but this is 3 stacks, all distributed in the same way.
