@WithSpan and customTextMapPropagator #2438
Description
Describe the bug
This is related to #2436
@WithSpan could be more robust if there is a way to specify custom Propagator to extract parent trace.
Even though there is parent trace a new trace is created.
This limits the use of @WithSpan, if a library is not instrumented. And we would be forced to create span the hard way.
Steps to reproduce
use this project : https://github.com/mnadeem/boot-opentelemetry-tempo
