Because the frame is not official yet so

  if (NILP (Vrun_hooks) || !(f->official))

will return immediately.

I suppose the OP confused two calls of adjust_frame_size - the one at
line 4609 and the one at line 4678.  The latter indeed does run the
functions on `window-configuration-change-hook' and breaks in
Fface_font.  It doesn't break on Windows or Gtk because there apparently
the sizes do not change any more.  I still don't know why the sizes
change on Motif/Lucid.
