Comment 3 for bug 1388978

I am guessing this test code may be flaky:

        self._drag_pointing_device_to_delete()
        if self.confirmRemoval:
            self.waitingConfirmationForRemoval.wait_for(True)

If the problem comes back, we can disable the test because these list items are going to be deprecated, and the new list items will have new tests, so better to spend our time on the new ones.
