LayeredDigraphLayout issue when there are links between nodes and their groups

[Ricecake]

I set the LayeredDigraphLayout both in Diagram and Group.
Here is the scenario:

It is correct to show the diagram above. But when I add the link from “Group010” to “Table”, GOjs seems to fall in a trap and Chrome fails to response.

I think there is some issue when layer calculation exists in nodes and their groups at the same time.
I want to know if the is method to filter out the link between “Group010” and “Table” in layer calculation to avoid this trap?

I cannot reproduce any problem. Here’s what I tried:

  function init() {
    var $ = go.GraphObject.make;

    myDiagram =
      $(go.Diagram, "myDiagramDiv",
          {
            initialContentAlignment: go.Spot.Center,  // for v1.*
            layout: $(go.LayeredDigraphLayout)
          });

    myDiagram.nodeTemplate =
      $(go.Node, "Auto",
        $(go.Shape,
          { fill: "white" },
          new go.Binding("fill", "color")),
        $(go.TextBlock,
          { margin: 8 },
          new go.Binding("text"))
      );

    myDiagram.groupTemplate =
      $(go.Group, "Vertical",
        {
          layout: $(go.LayeredDigraphLayout)
        },
      $(go.TextBlock, "group", { portId: "" },
          new go.Binding("text")),
        $(go.Panel, "Auto",
          $(go.Shape, { fill: "lightgray", strokeWidth: 4 },
            new go.Binding("stroke", "color")),
          $(go.Placeholder, { margin: 10 })
        )
      );

    myDiagram.model = new go.GraphLinksModel(
    [
      { key: 1, text: "Alpha", color: "lightblue", group: 3 },
      { key: 2, text: "Beta", color: "orange", group: 4 },
      { key: 3, text: "Gamma", color: "lightgreen", isGroup: true },
      { key: 4, text: "Delta", color: "pink", isGroup: true }
    ],
    [
      { from: 1, to: 2 },
      { from: 3, to: 4 }
    ]);
  }

This resulted in:

Thank you, walter. I found my gojs was not the latest version.
