Sankey error state

In https://github.com/plotly/plotly.py/issues/1536, @adurivault discovered a combination of Sankey links that causes Plotly.js to freeze up.

var fig = {
  "data": [
    {
      "link": {
        "source": [

        "target": [

        ]
      },
      "node": {
        "label": [
          "A",
          "B",
          "C",
          "D",
          "E"
        ]
      },
      "type": "sankey"
    }
  ],
  "layout": {}
}

Plotly.newPlot('myDiv', fig, {showSendToCloud: true});

Interestingly, if any single link is commented out, then the diagram renders successfully.
