When user middle clicks a link, most users must not expect to expose clipboard content to the web application. Therefore, we should stop firing paste event when user click a link with middle button. This patch makes ClickHandlerChild.handleEvent() prevent multiple action when it posts middle click event on a link. Note that even if middle click event is consumed, default event handler will dispatch paste event. Unfortunately, this is compatible behavior with the other browsers. Therefore, we cannot change this behavior with calling preventDefault() and this is the reason why this patch adds Event.preventMultipleActions(). Out of scope of this bug though, if there is an element which looks like a link but implemented with JS, web apps can steal clipboard content if user enables middle click event and user just wants to open the link in new tab. It might be better to stop dispatching paste event in any browsers and request to change each web apps.
