I attached a tiled image with the screenshots taken after each mousePress and mouseRelease pair which I got by the modified version of the test in JDK-8348299. As you can see in ItemEventTest-sequence.png, the items in the list are selected and deselected as expected, yet no events are dispatched. The test passes if I comment out test.testHandleEvent(), which means the events aren't received via the overridden `handleEvent` method. If ItemListener is added to the list, the events are received.
