I'm updating Jetpack Navigation from 2.3.4 to 2.4.2 and believe I have found a breaking change in my project.

Let's say I have a MainFragment and a SecondFragment. Launching SecondFragment from MainFragment (with safeArgs) works as expected. However, I also need to be able to launch a new instance of SecondFragment from SecondFragment with new arguments. I'm constructing a new navigation action and telling the navController to navigate to it. Before updating, I could see that this navigation action was taken, and I hit onCreateView and other lifecycle methods in my SecondFragment class.

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    val button = view.findViewById<Button>(R.id.myButton)

    button.setOnClickListener {
        val action = SecondFragmentDirections.newSecondFragment("coming from second")
        Log.d("SecondFragment", "click ${action.arguments.get("myArg")}")
        findNavController().navigate(action)
    }

    val text = view.findViewById<TextView>(R.id.message)
    text.text = safeArgs.myArg
}

Now with the update, my log statement there is being logged and is correct, but it seems like the navigation action never happens, as I'm never hitting onCreateView or onViewCreated, and my SecondFragment does not update with the new arguments.

I have a small reproducible example here: https://github.com/rahobbs/NavExperiments/tree/main/app/src/main/java/com/example/navexperiments
