not() and filter() not behaving correctly when used with $(array)

Description

If we create a jQuery object from an array, and then apply not() and filter() on that object, the result won't be correct.

The following code is used for testing. The top part (using selector, ie. $('tr') is the control showing the correct result as a comparison). The bottom part (creating an array and then creating a jQuery object based on them) is the incorrect result demonstrating this bug.

The test is done on:

  • FF 3.6.3
  • IE 8.0.6001.18702
  • Chrome 4.1.249.1064 unknown (45376)

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
  var logstr = '';
  function log(s) { logstr += s + '\\n'; }

  function test(s, o) {
    with (o) {
      log(s + ' length: ' + length);  
      log(s + ' not(".bottom"): ' + not('.bottom').length);  
      log(s + ' filter(".bottom"): ' + filter('.bottom').length);  
      log(s + ' not("tr.bottom"): ' + not('tr.bottom').length);  
      log(s + ' filter("tr.bottom"): ' + filter('tr.bottom').length);  
    }
  }

  var tr = $('tr');
  test('selector', tr);

  log('');

  var rows = new Array(), i = 0;
  tr.each(function() { rows[i] = $(this); i++; });
  test('array', $(rows));

  alert(logstr);
});
