Sorry, this problem exists on both emacs-30 and on master (it was
unfortunately broken since nnfeed and nnatom were added to Emacs last
year).

I'm currently going over nnfeed and nnatom when I have free time to
hopefully find any issues I missed before Emacs 30 is released (as it
will be the first stable release to include them).
