The problem is that `(funcall prog-mode)' in `org-html-fontify-code'
enables fci-mode. So disabling it in `org-export-before-parsing-hook' won't
work.

But your reply gave me another idea..

I can remove enabling of fci-mode from my prog mode hook in
`org-export-before-parsing-hook'.

But then where can I rehook it? I can't find a hook like
`org-export-after-processing-hook'. Can you suggest a hook that can work
for this use case?
