**Steps to replicate the issue** (include links if applicable):All changes to the #checkuser repo are currently blocked by failing #discussiontools tests. For example, https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CheckUser/+/1245267?tab=checks has some #discussiontools tests failing consistently
Please see this PR https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CheckUser/+/1245267?tab=checks. In the CI pipeline it has tests from DiscussionTools that are failing
