It fails because the number of clicks in the event detail is hardcoded to 2 or 3 in QWebPage depending on the click event. I can't imagine there are pages out there depending on 5 clicks in the detail of an event handlers, so presumably we should just file Qt-specific results? (Might be an idea to update the output of the test to mention Qt-specific behaviour)
