+Combine coverage data from multiple jobs, keeping the data only from the most recent attempt from each job.
+Coverage artifacts must be named using the format: "Coverage $(System.JobAttempt) {StableUniqueNameForEachJob}"
+The recommended coverage artifact name format is: Coverage $(System.JobAttempt) $(System.StageDisplayName) $(System.JobDisplayName)
+Keep in mind that Azure Pipelines does not enforce unique job display names (only names).
+It is up to pipeline authors to avoid name collisions when deviating from the recommended format.
