Coroutine is unstable in notebook

[Cyberavater]

sample code

val scope = CoroutineScope(Dispatchers.Default)
val sharedFlow = flow {
    while (true) {
        emit(Unit)
        delay(1.seconds)
    }
}.onEach {
    println("Emitted")
}.shareIn(
    scope,
    started = SharingStarted.WhileSubscribed(),
)

val job = Job()
runBlocking {
    //5 listeners
    repeat(5) { listenerId ->
        launch(job) {
            sharedFlow.collect {
                println("Collected by $listenerId")
            }
        }
    }

    delay(10.seconds)
    job.complete()
    println("Done")
}

Output last part:

This is problematic, you won't see this happen while running as regular jvm project.
