BackgroundDoubleClicked not working with Freehand

GoJS
1

We are using BackgroundDoubleClicked diagram event. But when using Freehand (Freehand Drawing Tool) its not working.

To a copy of the Freehand Drawing sample I added a “BackgroundDoubleClicked” DiagramEvent listener, as follows:

      $(go.Diagram, "myDiagramDiv",
        {
          "BackgroundDoubleClicked": function(e) {
            alert(e.diagram.lastInput.documentPoint)
          }
        }
      );

And it worked as expected – whenever I double-clicked in the background (i.e. not on any shape) I got the alert showing where I had clicked in document coordinates.

It doesnt work in drowing tool is enabled but works on selection mode.

When I run your CodePen, I find that I get the alert on background double-click both in Select mode and in Draw mode.
