Description
The use case is e.g. polling mechanism in e.g. RabbitMQ.
We would create an Observation (span X) when polling starts (at which point there is no message). Next, when the message arrives we would create a child Observation. However the span Y will not be a child of the span X, because it will be populated with tracing information from the headers. What we should do though is to link span Y to span X.

Research direction
The issue names no file, test, or entry point. Begin by locating the Observation handling for RPC spans and RabbitMQ polling, then identify existing tracing-link tests; done means span Y is linked to span X when polling has a parent and tracing headers are present.
