    Focus new tabs when created from the New dialog
    
    The recent change to tab handling to avoid switching pages when
    opening multiple tabs at once broke the New dialog, as in its case the
    parent tab could be anything. This change adds manual tab focus logic
    to the dialog.
    
    Based on a patch from Peter Tyser.
