(Re)linkgTool temporary node style: size being ignored

@nmfa wrote:

We have nodes with ports, and the ports are highlighted when their link is selected. As such the temporaryToNode and temporaryFromNode have a style set:

    tempNodeStyle = this.getNodeStyleTemplate();
    linkingTool.temporaryToNode = tempNodeStyle;
    linkingTool.temporaryToPort = tempNodeStyle.port;


getNodeStyleTemplate(): go.Node {
    return this.$(go.Node, {layerName: 'Tool'},
            this.$(go.Shape, 'Circle',
            {
                fill: null,
                portId: '',
                desiredSize: new go.Size(8, 8),
                stroke: 'lime', //this.gojsDiagramStyleProvider.getLinkDuringDrawStyle().stroke,
                strokeWidth: Number(this.gojsDiagramStyleProvider.getLinkDuringDrawStyle().strokeWidth.replace('px', ''))
            }));
}

The stroke change is to prove to myself that I'm looking at the right thing, and works as expected. However, the desiredSize is being ignored. What I am after, is the overlay being the same size as the existing port, but at the moment it seems one pixel larger, and the size seems unalterable.
