refreshDots not called when ListAdapter.submitList

[li2]

I use androidx.recyclerview.widget.ListAdapter and call submitList to update recyclerView, however, the dots were not showing until I call notifyDataSetChanged instead.

 fun setViewPager2(viewPager2: ViewPager2) {
   viewPager2.adapter!!.registerAdapterDataObserver(object : AdapterDataObserver() {
     override fun onChanged() {
       super.onChanged()
       // I added breakpoint here,
       // and this callback is not trriggered when call submitList
       refreshDots()
     }
   })
 }

I've got the same issue with ListAdapter. When calling submitList to push the data to the ViewPager2's adapter, no dots are displayed until notifyDataSetChanged() is called.
