Component used: lifecycle-runtime-ktx
Version used: 2.2.0-alpha01 up to 2.3.0-alpha07

The following example should print "1", "2" then "3" but prints "1", "3", "2":

lifecycleScope.launchWhenResumed {
  launch {
    println("1")
    yield()
    println("3")
  }
  println("2")
}

A similar problem existed in Dispatchers.Main but was fixed: https://github.com/Kotlin/kotlinx.coroutines/issues/1474

To reproduce the issue. Open a fragment for example then request permission. send the app to background, open it again from recent apps. it will crash with the above exception.
