    css: Handle font-size changes properly
    
    Changing font size does not cause widgets to update their size
    properly anymore, since we forgot an invalidation flag. The
    problem can be observed e.g. by running gtk3-demo and calling
    
    gsettings set org.gnome.desktop.interface font-name "Cantarell 22"
