Fragment and viewLifecycleOwner deviation

I'm collecting a flow on the viewLifecycleOwner. It flows on Dispatchers.Default, but the collection itself takes place on Dispatchers.Main.

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    viewLifecycleOwner.lifecycleScope.launch {
        flow.flowOn(Default).collect {
            requireContext()
        }
    }
}

In one occation I found the IllegalStateException stating, that the fragment is not attached.

IllegalStateException: Fragment Test not attached to a context.

I assumed that the collection of the flow would be canceled before the fragment is detached.

How is it possible for the coroutine to resume on a detached fragment?
