I have a Python program that is automatically instrumented by OpenTelemetry (OTel), and the traces are exported to a log file.

I noticed that whenever an exception is raised and unhandled, it terminates all open spans in the stack, and they are not exported to the log file. However, if I catch the exception and manually end the span, it gets recorded.

Is this the expected behavior, and if so, why?

Is there a way to configure OTel to save the spans even when they encounter an unhandled exception, and possibly add the exception as an event within the span?
