         * In order to ensure that the pin action toolbar sets its size 
         * correctly, the pin action should set its visiblity before we call updatePinActionToolbar().
         * 
         * In other words we always want the PinActionContributionItem to be notified before the 
         * WorkbenchActionBuilder.
