But the OP says it happens on all systems (OS X, Linux, BSD)
(which seems odd to me).

Anyway, reproduced on a GNUstep build (only) on GNU/Linux.

"Set Default Font" uses ns-popup-font-panel, which does not appear to
add the 'customized-face property to the default face, so
menu-bar-options-save finds nothing to do. Probably related, it only
changes the current frame, not all frames.

In fact, this is good old http://debbugs.gnu.org/2845
