bug#51768: 29.0.50; User font settings are ignored (Win10)

[Arash Esbati]

Hi all,

I've customized my fonts like this:

(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(default ((t (:family "Source Code Pro Medium" :foundry "outline" :slant 
normal :weight medium :height 90 :width normal))))
 '(fixed-pitch ((t (:inherity default)))))

Emacs from master (3e23494394) ignores these settings and starts with
Arial which looks likte this:

My last build (41b1fa05c7) works as expected.  To reproduce:

1) Make a minimal init file with the code above
2) Start emacs

This is on Win10 with Msys2.

Best, Arash
