Rail focus issue when D-pad UP

[Anuragjain01]

Hi @rubensousa i am facing one issue is
i have 5 rails in dpadrecylerview and let say my focus on third rail and i add new rail added at 2nd position then when i move d-pad up then focus not move to up it remove from d-pad recyclerview and when i press-d-pad down and then left or right then its working fine. and when rail is added below the rail that have already focus then its working fine.
val diffCallback = RowDiffCallback(items, rows)
val diffResult = DiffUtil.calculateDiff(diffCallback)
items.clear()
items.addAll(rows)
diffResult.dispatchUpdatesTo(this)

    if (recyclerView?.hasFocus()==true) {
        recyclerView?.requestLayout()
    }

and after add rail if i do recyclerView?.requestLayout() then its working but issue will in performance

@Anuragjain01 that DiffUtil usage doesn't seem correct. Can you please create a sample that showcases this issue? Otherwise I can't really help
