Chromeアップデート後JointJSのportsが変な所にある

Transform list APIが変な動作をするせいで起こるらしい
改善はVectorizer transformをオーバーライドすればいい

V.matrixToTransformString = function(matrix) {
   matrix || (matrix = true);
   return 'matrix(' + [
       matrix.a || 1,
       matrix.b || 0,
       matrix.c || 0,
       matrix.d || 1,
       matrix.e || 0,
       matrix.f || 0
   ] + ')';
};

 V.prototype.transform = function(matrix, opt) {

   var node = this.node;
   if (V.isUndefined(matrix)) {
       return (node.parentNode)
           ? this.getTransformToElement(node.parentNode)
           : node.getScreenCTM();
   }

   if (opt && opt.absolute) {
       return this.attr('transform', V.matrixToTransformString(matrix));
   }

   var svgTransform = V.createSVGTransform(matrix);
   node.transform.baseVal.appendItem(svgTransform);
   return this;
};

coffee version

V.matrixToTransformString = (matrix)  ->
  matrix || (matrix = true)
  return 'matrix(' + [
      matrix.a || 1,
      matrix.b || 0,
      matrix.c || 0,
      matrix.d || 1,
      matrix.e || 0,
      matrix.f || 0
    ] + ')'


V.prototype.transform = (matrix, opt) ->

  if V.isUndefined(matrix)
    if (node.parentNode)

    else
      return node.getScreenCTM()


  if (opt && opt.absolute)

  return this
