Apologise for the error! I think I was building an old version of the docs and
after the clarification from Andrew about refreshing the files with ./configure
I was able to reproduce the issue.
I didn't put any tag like Reported-by/Suggested-by because I don't know if they
can be put here? Anyway I guess it can be done on commit, Andrew reported the
issue and Michal was quick enough to suggest the fix before I've started working
on it :)
