xref in a narrowed buffer?

Iʼm not sure this counts as a bug, so I thought Iʼd ask:

    visit src/fontset.c, move point until youʼre inside 'set_fontset_font'
    C-x n d ; narrow-to-defun
    M-. <RET> ; xref-find-definitions
    C-n <RET> ; xref-goto-xref

    => echo area shows: Rerun etags: `^#define FONTSET_ADD(' not found
    in /Users/rpluim/repos/emacs/src/fontset.c

Should 'xref-goto-ref' widen the buffer before attempting to jump to
the definition? Or should 'xref-find-definitions' not show definitions
that are outside the narrowed area?
