Medium - Some functionality impacted

Start in the Browser Portlet and reproduce the locked Menu Link flow using the listed steps, including navigating away and signing in as another user. Trace where the PortletException reaches the error screen. Done means either leaving the edit screen releases the lock or the error clearly tells users that the Menu Link is locked.
