title: Clone isn't cloning select values
body: <p>I didn't expect it but the following test fails on the cloned value check:</p>
  
  <pre><code>test("clone should retain values of select", function() {
      var select = $("&lt;select&gt;").append($("&lt;option&gt;")
                                .val("1"))
                                .append($("&lt;option&gt;")
                                .val("2"));
      $(select).val("2");
      equals($(select).find("option:selected").val(), "2", "expect 2");
      var clone = $(select).clone();
      equals($(clone).find("option:selected").val(), "2", "expect 2");
  });
  </code></pre>
  
  <p>Is this right?</p>
