Theme parsing error on TAG:3.2

(update-manager:5692): Gtk-WARNING **: 16:29:02.806: Theme parsing error: gtk-widgets.css:238:26: Missing closing bracket for :not()

when I open a dialog, the above error message appeared on my terminal.
maybe the problem file is ./gtk-3.20/gtk-widgets.css

My Linux: Ubuntu18.04
Gnome: 3.20
Theme Version: from TAG:3.2

Hello. I opened the file at the line 235, and nothing seems to be wrong. That's the code:

   button:focus:not(combobox button):not(:backdrop) {
    background-image: linear-gradient(to bottom, shade(@selected_bg_color, 1.25), shade(@selected_bg_color, 0.99) );
    box-shadow: 0 0 1px 1px shade(@theme_selected_bg_color, 1.65);
    color: @theme_selected_fg_color;
    border-color: shade(@theme_selected_bg_color, 1.5);
}

Still, I'm seeing the warning . Yes, the error occurs at the file ... /gtk-3.20/gtk-widgets.css

version 4.0 should fix this
