Is this script provided by Pygments or from the Docutils sandbox?
https://docutils.sourceforge.io/sandbox/stylesheets/pygments_css2sty.py

There were several changes to Pygments since the last update of the
Docutils sandbox script 2013-03-27, indeed.

On my Debian/stable system, with Pygments version 2.3.1, the output of
`pygmentize -f html -S colorful` does not contain these lines this further
indicates that there was a "recent" addition.

Volunteers/patches welcome.
