Description

The expandable icons (plus minus icons) in the tree view grid lag while scrolling vertically on a touch device, i.e. they get slightly detached from the corresponding row. When we stop scrolling, they align themselves correctly. But then again upon further scrolling the lag persists.

Contributor guide

Research direction
Investigate the rendering behavior of expandable icons on touch devices. Test on a real device or emulator. Check for any debouncing or throttling in scroll handlers. Look for CSS properties like 'will change' or 'transform' that might improve performance. Review the code for the tree view grid component.
