For example, visit an image, type `C-h i', resize the window, type `C-x k RET'
(not `q', because `q' restores previous window sizes), then the image is not
updated to fit the resized window.

Trying to put to image-mode:
(add-hook 'buffer-list-update-hook
(lambda () (message "buffer-list-update-hook %S"
(current-buffer))) nil t)
shows in *Messages* that it's called only when navigating away from the
image-mode buffer, but not when coming back to the image-mode buffer, e.g.
`C-x <left>', then resize the window, then type `C-x <right>',
it's not called. Also it's not called in another direction:
`C-x <right>', then resize the window, then type `C-x <left>'.
