Start with tests/Aspire.Playground.Tests/BlazorWasmHostingTests.cs at lines 167 and 176, then review the linked CI job and its logs or artifact. Re-run StandaloneBlazorWasm_BrowserRendersWeatherAndSendsTelemetry and trace the failed request to /app/_otlp/v1/logs. Done means the test consistently observes the expected telemetry request without the Assert.Contains failure.
