Is there a better way to “launch flow collection but suspend until the collection is ready”?
Without this workaround (i.e. `.onEach { … }.launchIn(…)`) elements can be missed if they’re emitted shortly after this.

```launch(start = CoroutineStart.UNDISPATCHED) {
    collect { action(it) }
}```

That does something very different :thinking_face:
It delays the start of the collection instead the start of the emission.

the `launch` doesn't return until `collect` suspends, after which it is safe to start emitting. is that not what you want to wait for?
