Hi,
since pandoc 2.17.1.1-1, the latex generated from rst by [this script]
fails to build with:

Responsible for this is pandoc as evident from a debbisect run with this
reproducer script test.sh:
#!/bin/sh

chroot "$1" runuser -u user -- env --chdir=/home/user sh -e << EOF
pip3 install sphinx
wget https://github.com/rsms/inter/releases/download/v3.15/Inter-3.15.zip

unzip Inter-3.15.zip
mv 'Inter Desktop' /home/user/.local/share/fonts/

Bingo! Using the --standalone option to pandoc indeed made it generate the
definition for the Highlighting and Verbatim environments.
Is there a way to tell pandoc to just give me the preamble that --standalone
produces so that nothing breaks the next time pandoc is updated?
Anyways, not pandoc's fault, so closing this bug.
Thanks!
