Using the draw polygon, the isSelfIntersecting bool is only true after vertex-add but not draw-complete

Using the draw polygon (PolygonDrawAction), the isSelfIntersecting bool is only true after vertex-add but not draw-complete.  So if I draw a polygon and create a self intersecting polygon, if I just double click ie draw-complete event the  isSelfIntersecting bool stays false.  I need to add a vertex ie vertex-add after I draw a self intersecting polygon and then double click to draw complete and then the isSelfIntersecting bool is set to true.  so my question is there a way to force a vertex-add at the draw-complete location or do I need to evaluate the vertices and find the self intersecting geometry manually by evaluating the vertices?

OK so I just check to see if the polygon isSimple  on draw complete and it is not .isSelfIntersecting.

 

    // function that checks if the polygon intersects itself

    public isSelfIntersecting = (polygon) => {

        // The quickest way to see if the poly is selfintersecting with out the esri .isSelfIntersecting bool is to check to see if the poly is simple

        const isSimplePoly = polygon.geometry as __esri.Polygon; // Avoids TypeScript errors when building the app

        if (this.esriLibrary.GeometryEngine.isSimple(isSimplePoly)) {

            return true; // Return true if the Polygon is Simple

        } else {

            return false; //Return false if it is not simple

        }

    };
