Fixes an oversight on my part: when spans are propagated the datadog tracer expects the use of a propagator to manually call
tracer.context_provider.activate
. This is not done by the opentracer. As such the context is not activated and any subsequent spans created will not inherit from the propagated context.I was able to replicate #606 and to create a test to cover this logic.
Fixes #606.
