The following unrelated patches fail CI, for reasons not connected (as far as I can tell) with the patches themselves
https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikibaseMediaInfo/+/606187
https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikibaseMediaInfo/+/607550
For example, patch [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikibaseMediaInfo/+/607550 | 607550 ]] only makes a couple of small JavaScript changes, but the [[ https://integration.wikimedia.org/ci/job/mwgate-node10-docker/134546/console | mwgate-node10-docker/134546 ]] jobs fails with:
```
