    Unbreak GtkComboBox::button-sensitivity
    
    Fixed the button-sensivity patch done to GtkComboBox to account for
    changes in appearance (changes to the appears-as-list style property).
    Also, in list-mode, the event box that has been created below the cell
    view also needs to have its sensitivity updated.
