title: requireJS - Mismatched anonymous define() module in multipage shim
body: <p>I'm following the multipage shim sharing pattern here:
  <a href="https://github.com/requirejs/example-multipage-shim" rel="noreferrer">https://github.com/requirejs/example-multipage-shim</a></p>
  
  <p>I'm using the same common.js and have a very similar and simple set up:</p>
  
  <pre><code>&lt;script src="js/library/requirejs/require.min.js"&gt;&lt;/script&gt;
  &lt;script&gt;
  require(['./js/config/common'], function (common) {
    //go on...
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Everything loads fine and I can continue running operations inside the require closure, but I keep getting an error in Firefox complaining about a mismatched anonymous define() module with the above code. Given how simple it is and that I'm following the example pattern pretty much exactly I'm a bit confused as to why I'm getting it. I haven't used define() anywhere. Has something in requireJS changed in the last 24 days (since the multipage git repo was updated)?</p>
