Document Classes ⇒ vecarrow in svmono doesn't work

[user49915]

The documentation of svmono v5.6 from http://www.springer.com/gp/authors-edit ... ation/5636 says in refguide.pdf:

vecarrow depicts vectors with an arrow above when \vec-command is used

However, feeding pdflatex with

Code: Select all

\documentclass[vecarrow]{svmono}% v5.6 from https://resource-cms.springernature.com/springer-cms/rest/v1/content/20566/data/v10
\begin{document}
\(C\vec{C}\)
\end{document}

results in

No arrow is printed.

Any bugfix, ideally by means of \patchcmd or similar so that I don't have to hack svmono? I cannot get myself through to Springer (my e-mails got rejected on the SMTP level).
