    togglebutton: always set PRELIGHT state when in_button = TRUE
    
    Previously, we would avoid setting the prelight state flag when
    button_down was TRUE and draw_indicator = FALSE, which is the normal
    case of a GtkToggleButton during a mouse press.
    It looks like this behavior was introduced a long time ago with commit
    b94e6c0a8036a0489ac8ca71de75ba7611218e50. I believe the reason was that
    a widget in GTK2 couldn't have more than a single state (e.g.
    hover+active) at a given moment.
