Because as long as at least one GUI frame is created, Emacs doesn't
have access to GUI capabilities that can affect the selected fonts.
Assuming that you start Emacs with -nw or as a daemon, you need to
have face customizations that require GUI features in
after-make-frame-functions, not in your init file.
