title: QUnit strange behavior with fixture, tests alternately failing and passing
body: <p>I have the following set up in QUnit:</p>
  
  <pre><code>/* Dozen or so previous tests here */
  
  test("Test some markup generation", function () {
  
      $('#qunit-fixture').plugin(); // jQuery plugin: Generates a table
  
      var rows = $('#qunit-fixture table tbody tr');
      count = rows.length;  // Count the rows
      console.log(count);
  
      equal(count, "96", "Expect the number of rows to be 96");
  });
  </code></pre>
  
  <p>When it runs, or when I refresh the browser it alternately fails this test showing count = 0, or passes this and fails all the previous tests. There are no global variables defined outside the tests. If I set count to 96 by hand everything passes fine, or if I remove this test, or all the previous tests, everything also passes. I am wondering if anyone has run into this behavior? I've used QUnit quite a bit and have not encountered this before.</p>
