Attempting to load browser-js on node. I can make a fake window and load it, but if I turn `global` into the fake window, it fails with vm.runInNewContext(source, fakewindow); ^ ReferenceError: window is not defined

  'use strict';
  var fakewindow;
  var fakedocument, fakenode;

  fakedocument = {
    createDocumentFragment: function() {
      return {
        appendChild: function() {}
      };
    },
    documentElement: {},
    nodeType: 9,
    attachEvent: function() {}
  };

  fakenode = {
    setAttribute: function() {},
    getElementsByTagName: function() {
      return {};
    },
    ownerDocument: fakedocument
  };

  fakedocument.createElement = function() {
    return fakenode;
  };
  
  if (typeof window !== 'undefined') {
    fakewindow = window;
    fakewindow.loadGlobalScript = function() {};
  } else if (typeof global !== 'undefined') {
    fakewindow = {};
    //fakewindow = global; // If this is uncommeted, it fails
    fakewindow.window = fakewindow;

    fakewindow.console || (fakewindow.console = console);

Oh, how did I miss your comment?

Yeah, it was for a testing framework. We eventually went with Testem + PhantomJs, and stopped trying to run on node at all.

I guess that the global object is actually derived from some kind of "default globals" object, and only hasOwnProperty of things you define on it directly? that's pretty cool, except that it breaks this use case. (Which is, pretty far from normal, I admit.)
