I simply navigated to the Project > Volumes panel, then shrunk the browser width to match the one in the attached screenshot. Upon further examination, I can see that this behavior is exhibited in many of the panels. For an example of a panel that does not exhibit this problem when shrunk down, look at Project > Images. I am using Chrome under Linux (Ubuntu 14.04)
