A very quick fix for [**Zombie**](https://github.com/assaf/zombie) to permit to crawl correctly webpages with attributes on the html tag (eg: html lang="en").

var Interaction;

Interaction = (function() {
  function Interaction(browser) {
    var alertFns, confirmCanned, confirmFns, promptCanned, promptFns, prompts;
    prompts = [];

        return confirmFns.push(question);
      } else {
        return confirmCanned[question] = !!response;
      }
    };
    promptFns = [];
    promptCanned = {};
    this.onprompt = function(message, response) {
      if (typeof message === "function") {
        return promptFns.push(message);
      } else {
        return promptCanned[message] = response;
      }
    };
    this.prompted = function(message) {
      return prompts.indexOf(message) >= 0;
    };
    this.extend = function(window) {
      window.alert = function(message) {
        var fn, _i, _len;
        browser.emit("alert", message);
        prompts.push(message);
        for (_i = 0, _len = alertFns.length; _i < _len; _i++) {

        browser.emit("confirm", question);

      return window.prompt = function(message, defaultValue) {

        prompts.push(message);
        response = promptCanned[message];

  return Interaction;
