  37 <br>This test does the following via EventSender:<br>
  38 1. Click and drag the div scrollbar to a middle point.<br>
  39 2. Click and drag again, this time down and to right, with the mouseup occurring in a parent frame.<br>
  40 3. Move the mouse back into the div with the scrollbar.<br>
  41 Per https://bugs.webkit.org/show_bug.cgi?id=73097, because the div with the scrollbar had a mousedown event that called preventDefault(),
  42 the mouse moves would not properly be handled by the scrollbar. We pass if the div's scrollTop property is the same after all 3 steps.
