//  This override is needed because LCMAttachment intercepts mouse clicks, tracks
//  the click, and handles it if the click is on a context menu. We don't want so
//  complete a solution. In our case, mozilla handles the click, determines that
//  it's a context menu click and then calls nsIContextMenuListener::OnShowContextMenu.
//  This override allows DoContextMenuClick to be called after the click.
