Placeholder in group Template not working with customResizeTool and rotateMultipleTool

Hi Walter,
I am using placeholder in my grouptemplate and when i rotate the group panel the shapes it contains are moving outside this panel Also it doesn't has smart size for all the shapes because i have set desired size of this panel to desiredSize:new go.Size(270, 200),if i set minsize and use placeholder it cover all the shapes accurately but in this case it stops resizing.What i want is group panel should cover all sizes shapes properly and all the shapes should resize and rotate with the group panel.

here is my groupTemplate code

  myDiagram.groupTemplate =
  GO(go.Group, "Auto",
    {rotatable:true,resizable:true,resizeObjectName: "SHAPE",locationObjectName: "SHAPE",resizeAdornmentTemplate: //showing resize panel in right bottom corner only
          GO(go.Adornment, "Spot",
            GO(go.Placeholder, { padding: 5/2 }),  // half the SHAPE.strokeWidth
            GO(go.Shape, { alignment: go.Spot.Right, width: 6, height: 6, stroke: "dodgerblue", fill: "lightblue", cursor: "e-resize" }),
            GO(go.Shape, { alignment: go.Spot.BottomRight, width: 6, height: 6, stroke: "dodgerblue", fill: "lightblue", cursor: "se-resize" }),
            GO(go.Shape, { alignment: go.Spot.Bottom, width: 6, height: 6, stroke: "dodgerblue", fill: "lightblue", cursor: "s-resize" })
          ),ungroupable: true},
    new go.Binding("location", "loc",go.Point.parse).makeTwoWay(go.Point.stringify),
    new go.Binding("angle", "ang").makeTwoWay(),

    GO(go.Panel, "Auto",
      GO(go.Shape, "RoundedRectangle",  // surrounds the Placeholder
      { name:"SHAPE",
      parameter1: 14,
      fill: "transparent",
      desiredSize:new go.Size(270, 200),
      stroke:"transparent"
      // minSize: new go.Size(270, 200)
      }),
       // new go.Binding("desiredSize", "size", go.Size.parse).makeTwoWay(go.Size.stringify),
     // GO(go.Placeholder,    // represents the area of all member parts,
    //  { padding: 5}),  // with some extra padding around them
      GO(go.TextBlock,
        {
        font: "bold 14px sans-serif",
        stroke:"black",
        alignment: go.Spot.Center,
        wrap: go.TextBlock.WrapFit,
        editable: true
        },
        new go.Binding("font", "fontstyle"),
        new go.Binding("text", "text").makeTwoWay(),
        new go.Binding("stroke", "textcolor"))
    )
  );

here is the diagram i get

currently its resizing and rotating correctly but the problem is i want to use plcaeholder and minsize in group template so that group panel contains the whole shape.
