Can GtkPopoverMenu flags be made into a property?
I'm exploring using UI files to create menus and see no way to set the flags for nested submenus, other than to create a popover in code using
gtk_popover_menu_new_from_model_full(). Will an MR to make flags a property be acceptable, so that we could set the
:flags before the
:menu-model in a UI file and thus get nesting there?
