It was generated by an earlier version of our automated bug-fix pipeline whose live-test step ran whole-module tests, which produced mis-targeted and environmental failures unrelated to the change. The pipeline now runs only the test files touched by the PR. This issue will be re-worked from scratch by the updated pipeline. |
