Test Case

When multiple displays are assigned to the same counter i.e. like in this case:
   #testView:before {
    content: "First Counter:" counters(test, ".") " Second Counter:" counters(test, ".");
   }
And the counter value changes, only the first display is invalidated. Which causes the second display to show the wrong value and a debug mode assertion on page tear down.
The error is in CounterNode::resetCounters which iterates the list of display renderers incorrectly.
