testMouseOverNonTrigger() {
    initCard();

    // Mouse over correct element fires trigger
    showDelay = 500;
    testingEvents.fireMouseOverEvent(john, elsewhere);
    timer.tick(showDelay);

    // Mouse over and out other element does nothing
    triggeredElement = null;
    testingEvents.fireMouseOverEvent(jane, elsewhere);
    timer.tick(showDelay + 1);
    assertNull(triggeredElement);
  }
Verify that mousing over non-triggering elements don't interfere.
