Start with test/tracing/request.test.ts and the instrumentOutgoingRequests test named in the issue, then inspect the linked Browser Unit Tests run for the failure details. Reproduce the flake and identify why the QUERY XHR span's method attribute is intermittent; done means the test passes reliably without weakening its assertion.
