JSViz Kills Undo and Redo


I'm on 7.11 and have installed JSViz, which as far as I know is functioning totally normally, but anytime I introduce a JSViz visualization to a library, the undo and redo buttons as well as the options under the Edit menu gray out and no longer work. Even if I go on and do more changes, it continues to be dead. 

I was wondering if this is a known problem or something wrong on my end with the JSViz install.

Any insight would be greatly appreciated, thank you!
