This fixes an issue, where someone would call
span.ToBaggage
to fetch theDynamicSamplingContext
to attach it to an outgoing HTTP request "baggage" header or to render it in an HTML template as a "baggage" meta tag before the transaction is finished.We need to freeze the DynamicSamplingContext in such cases, as any mutations after the DynamicSamplingContext was propagated to a downstream SDK mess up DynamicSampling.
