//! This test sets a global subscriber so that the sender half of the channel
//! inside the subscriber is never dropped. It tests that the receiver can be closed
//! manually via the shutdown signal that is sent once the `Future` passed to
//! `Runtime::on` finishes.
//!
//! Addresses https://github.com/QnnOkabayashi/tracing-forest/issues/4
