Evaluate:
(defun jpk/next-error-hook ()
(let ((win (get-buffer-window next-error-last-buffer)))
(when (window-live-p win)
(with-selected-window win ;; breaks with xref
(message "window: %s" win)))))
(add-hook 'next-error-hook #'jpk/next-error-hook)
Run xref-find-references on e.g. add-hook
Run next-error or previous-error at least twice.
Repeating next-error doesn't find the next match after the 2nd invocation.
Running previous-error behaves similarly. I can use a mouse to click on an
any match, but next/previous-error will still only move between the clicked
match and the next. I can only cycle between two matches.
For reference, this is my original hook:
(defun jpk/next-error-hook ()
(let ((win (get-buffer-window next-error-last-buffer))
(buf (buffer-name next-error-last-buffer))
(recenter-redisplay nil))
(when (window-live-p win)
(with-selected-window win
(recenter)))))
