Any backup file is opened as if the file name did not contain the backup
suffix:

`auto-mode-alist' contains:

 ("\\.~?[0-9]+\\.[0-9][-.0-9]*~?\\'" nil t)
 ("\\.\\(?:orig\\|in\\|[bB][aA][kK]\\)\\'" nil t)

meaning "if file name matches, strip the match and try determining major
mode again"

I guess we could fix this.
Though, I'd prefer if Emacs provided basic functionality to strip backup
suffix: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=60929
