very unsuprising, these are not widgets designed to display text (though
they can be used to do so in various ways.)

there are ways of drawing a Pango layout that would pay attention to the
atttributes you are trying to set. however, these are not the ways that
are used by a Gtk::Label in its expose event handling.

Pango has many more uses than just Gtk::Label, and some of those other
uses will use those attributes. Pango is usable outside of GTK entirely,
for example.
