A workaround is to manually specify that "DejaVu Maath TeX Gyre" should
be used:

   (defun font--configure (&optional frame)
     (let ((font (font-spec :name "DejaVu Math TeX Gyre")))
       (set-fontset-font t '(#x1D400 . #x1D7FF) font frame)))
   (add-hook 'after-make-frame-functions #'font--configure)
   (font--configure)
