Doesn't it only do that if font-use-system-font is t? Here is the
relevant part of dynamic-setting.el:
;; Just redraw the existing fonts on all frames:
(dolist (f frame-list)
(let ((frame-font
(or (font-get (face-attribute 'default :font f 'default)
:user-spec) <=====
this should return "Cascadia Mono"... what does it return for you?
