🐛 Describe

If the list is redrawn when the first item visible on the screen is out of the screen, the last item exposed on the screen is not drawn.

🐌 Steps to reproduce

1. Scroll the list so that the first item is off-screen
2. In this case, the last item visible on the screen is not all exposed and a part must be outside the screen.
3. When RecyclerView's notifyDataSetChanged() function is called

🦋 Expected behavior

The last item is not drawn

🪲 Other info

my fix suggestion

override fun onLayoutChildren(recycler: RecyclerView.Recycler, state: RecyclerView.State) {
...
            if (sizeFilled == 0) {
                sizeFilled = if (orientation == VERTICAL) {
                    layoutRect.top
                } else {
                    layoutRect.left
                }
            }
            sizeFilled += item.size
