/**
 * Wraps a propagator so that no trace context is written onto outgoing requests while Faro is not
 * emitting signals for the current session. Faro withholds it for two reasons:
 *
 * - Faro is paused. Pausing already stops signals from being sent, but the OTel propagator is
 *   registered globally and kept injecting `traceparent`, which made a paused SDK look like it was
 *   still tracking. See https://github.com/grafana/faro-web-sdk/issues/710.
 * - The session is not part of the sample and `omitTraceContextForUnsampledSessions` is enabled.
 *   See https://github.com/grafana/faro-web-sdk/issues/2250.
 *
 * Extraction stays enabled in both cases: reading an incoming trace context sends nothing, and
 * dropping it would detach a resumed or later-sampled session from the trace it belongs to.
