Now that the workbench has some added functionality, some of its more basic functions are sluggish.

What I expected to happen was...:
After putting ingredients in the workbench, you should be able to rapidly click on the product box multiple times depending on how many items you want to make.

What actually happened was...:
I quickly clicked twice on the product box but only got items from the first click, forcing me to click a third time.

Steps to Reproduce:
1. Put wood planks in the workbench as if you wanted to make 8 sticks (2 wood planks, then another 2 above them).
2. Click twice rapidly on the product box.
3. You will only get sticks from the first click, and will have to click again to get the rest.
I use sticks as an example but it does the same thing for any item.
