Ember.js, strange characters added after body

Running this sample 'bare bones' self-contained example

<html>
<head>
  <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
  <script type="text/javascript" src="http://cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.0.beta.6.js"></script>
  <script type="text/javascript" src="http://dl.dropbox.com/u/3024625/ember.js"></script>
  <script type="text/javascript">
  $(window).load(function(){
    var App = Ember.Application.create({
      ready: function() {
        this.layout = App.ApplicationView.create();
        this.layout.appendTo('body');
      }
    });
    App.ApplicationView = Ember.View.extend({
      template: Ember.Handlebars.compile('<h1>Application</h1>')
    });
    App.initialize();
  });
  </script>

  <script type="text/x-handlebars" data-template-name="application">
    test
  </script>​
</head>
<body>
</body>
</html>

Gives this output:

<body class="ember-application">​

<div id="ember129" class="ember-view"><h1>Application</h1></div></body>

Notice the "​" characters. Looks like an encoding issue, but in another setup those chars take the form of a new line above all the page (that's why I noticed the problem).

Deleting the 

  <script type="text/x-handlebars" data-template-name="application">
    test
  </script>​

lines, make the characters go away.

I have this same issue with the latest Ember.js (master), and with a build from a month ago.

Anyone else had this problem?

Strange, it looks like this is reproduced by trailing empty character at the end of the line 23 in your provided code. If you delete it, it works - also with the unused template application.

I did some further investigation and it looks like the invisible character is a ZERO WIDTH SPACE, see http://www.ltg.ed.ac.uk/~richard/utf-8.cgi?input=%26%238203%3B&mode=char.
