nswindow - How do I disable the Show Tab Bar menu option in Sierra apps?

Question

I've got an app that uses a Toolbar in a NSWindow. I don't want users to be able to customize this toolbar for aesthetic reasons. In Sierra there's a new Menu option that gets inserted into "Menu > View" called Show Tab Bar. How do I disable this? Enabling it only seems to increase the tool bar's height as I don't have extra labels showing under the icons.

You can also do this on IB, on the Window’s attributes inspector
