Start with test/tracing/request.test.ts and the instrumentOutgoingRequests case named in the issue, then inspect the linked Browser Unit Tests run for the failure details. Reproduce the test behavior and identify why the QUERY fetch span assertion is intermittent; done means the test passes reliably in Browser Unit Tests.
