The L10n bot change https://gerrit.wikimedia.org/r/c/mediawiki/extensions/intersection/+/995166 had to be manually merged because the message translation included a <graph> tag, which is unrecognized by Jenkins job configuration:

The easy solution appears to be to replace <code><nowiki><DynamicPageList></nowiki></code> with <code><DynamicPageList></code>, similarly to T356549.
