Is there a way to show connections from compound nodes to the children in Cytoscape.js

I am exploring the potential of Cytoscape.js, and would like to know if it is possible to visualize connections from compound nodes (parents) to children within this node.

In the example below I would like to show the connection between the parent node 'b' and the children 'a' and 'c', but so far I am unsuccessful.

Minimal working example is given below below, and editable here: http://jsbin.com/lelinaduko/3/edit

    elements: {
        nodes: [
          { data: { id: 'a', parent: 'b' } },
          { data: { id: 'c', parent: 'b' } },
          { data: { id: 'd' } },
          { data: { id: 'e' } },
          { data: { id: 'f', parent: 'e' } },
          { data: { id: 'b' } }
        ],
        edges: [
          { data: { id: 'bd', source: 'b', target: 'd' } },
          { data: { id: 'eb', source: 'e', target: 'b' } },
          { data: { id: 'ca', source: 'c', target: 'a' } },
          { data: { id: 'ab', source: 'a', target: 'b' } },
          { data: { id: 'bc', source: 'b', target: 'c' } }

        ]
      },

It seems you found a bug:

https://github.com/cytoscape/cytoscape.js/issues/866

Use haystack edges instead if you want to work around the issue until a new release -- as those edges are unaffected.
