When has_span_streaming_enabled is True, the span is created but never entered as a context manager (no __enter__ call), and ended directly via .end() instead of __exit__. This skips the exception handling logic in StreamedSpan.__exit__ that sets status = SpanStatus.ERROR when an exception occurs. If a GraphQL operation throws an exception, the streaming span will be marked as 'ok' instead of 'error', losing important error information.
