Research direction
Investigate the provided Plnkr and video to reproduce the issue. Examine the grid's virtual scrolling implementation in files like 'GridRenderContainer.js' and 'GridRowController.js' to identify performance bottlenecks. Check Chrome DevTools performance timeline for layout thrashing or forced reflows. Review existing comments for partial solutions.
