    gtknotebook: Claim event sequence after pressing notebook arrow buttons
    
    When notebook tabs are reorderable, pressing the notebook arrow buttons to
    change the active tab results in tabs reordering unexpectedly.
    Claim the event sequence after pressing an arrow button to avoid conflicts
    with the motion/drag gesture used for reordering.
