That is actually not the default behavior – the default behavior is for the mouse wheel to scroll the diagram.

I think in your initialization of the Diagram you set the ToolManager.mouseWheelBehavior:

    $(go.Diagram, . . .,
      { . . .,
        // mouse wheel zooms instead of scrolls
        "toolManager.mouseWheelBehavior": go.ToolManager.WheelZoom
      })

The user can toggle the behavior interactively too, by clicking the mouse wheel, which is also a button.
