Describe the bug
If the caller closes the connection before the router has a chance to respond (e.g. broken pipe), the router fails to apply any span tag attributes using the response_context selector

To Reproduce
Steps to reproduce the behavior:

1. Configure router with response_context selector:

telemetry:
  instrumentation:
    spans:
      mode: spec_compliant
      router:
        attributes:
          graph-operation-type:
            response_context: operation_kind

2. Configure subgraph to wait 10s before responding to calls
3. Send request to router using curl
4. Cancel the request (ctrl-c) while the subgraph is waiting to respond
5. Observe that the graph-operation-type was not applied to the span tag

Expected behavior
response_context span tag attributes are still applied to the router span just as with other non-200 errors (e.g. if there is a 400 BAD REQUEST error, we still see all tag attributes from response_context selectors on the router span) even when we have a broken pipe

Router:

• OS: Amazon Linux 2023
• Version: 1.37.0
