After reviewing the problem, I realized there may have been a misunderstanding on my part regarding the core issue. My interpretation was centered around a specific use-case: when a card is selected for editing and the editor is switched to dark mode, returning to the previous screen resulted in a loss of scroll position. So, I made changes to preserve the scroll state under these conditions.

Main problem is that in onScroll() if (size > 0 && visibleItemCount <= 0) was being executed right ? Or is it something different ?

Oh okay its also failing tests
