@Nokel81 I've opened a PR with a fix: #10249. It changes rerunFailed to filter to only the failed test ids per file (using the existing testIds filter in interpretTaskModes), instead of rerunning every test in files that contain failures. Falls back to whole-file rerun if a file failed during collection.
