Major Chemistry dispenser ui is broke for me and some other people

[Mageziya]

A related minor UI bug, since this seems like a good place to mention it. You know how upon inserting a container into the chem-machine, it automatically opens the chem window? For me, the chemical buttons will never load in that window now. I have to close that window, and then open it again by clicking on the chem machine, for it to work and properly display all the buttons.
