[Message part 3 (message/rfc822, inline)]

From emacs -Q:
1) Open a lisp file
   (setq display-line-numbers-widen t)
   M-x display-line-numbers-mode
2) Move point inside a function
   M-x narrow-to-defun
3) M-x widen

After (2) the window shows line numbers relative to the start of
the buffer, as expected.

After (3), the window shows line numbers starting from 1 for the
narrowed region. After the next mouse or keyboard input, the line
numbers are displayed normally.

Thus it seems that when display-line-numbers-widen is non-nil the line
numbers are not recomputed after widen until then next input.
