_This issue was automatically created._

Start with suites/tracing/propagation/worker-worker-do-rpc/test.ts and the linked Cloudflare Integration Tests run to reproduce the three-level worker-to-Durable Object trace propagation failure. Trace the test's execution across the workers and Durable Object, then verify that the test passes reliably without intermittent failures.
