    mouse: Fix initial widget visibility
    
    We're showing all widgets on panel start up instead of selectively
    hiding non-relevant widgets since the gtk_widget_show_all() on the
    stack after creating the panel widget and adding it to the stack
    overrides the visibility decisions done while constructing the panel.
