The mediawiki-core-regression* jobs are run on post merge on a per branch basis. They need to be migrated to Zuul cloner to bring up mediawiki/vendor as well.
That is preventing mediawiki/vendor patches from landing in.

mediawiki-core-regression* jobs now use Zuul cloner
I have updated all jobs and cleared out the workspaces on all production and labs slaves. One less job to migrate to use mediawiki/vendor :-]
