The browser widget may be scrolled also by calling:
{code:java}
nsIDOMWindow.scrollTo(int xScroll, int yScroll)
{code}

And you should be able to listen to the browser scrolling events using something like this:
{code:java}
nsIDOMEventListener listener = new nsIDOMEventListener() { 
   public nsISupports queryInterface(String interfaceId) { 
      return interfaceId.equals(nsIDOMEventListener.NS_IDOMEVENTLISTENER_IID) ? this : null; 
   }
   public void handleEvent(nsIDOMEvent event) {
      int pageYOffset = queryInterface(window, nsIDOMWindowInternal.class).getPageYOffset();
      // scroll the source here
   }
}
queryInterface(window, nsIDOMEventTarget.class).addEventListener("scroll", listener, false);
{code}

> When Horizontal splitting with the Source Editor is set it would be nice to have switch to have row locked to keep the corresponding visual element on the same row as in the source part and vice versa.
