But same happens in dev samples too.

2. Focus the grid and start navigating using the ArrowDown key

3. Keep pressing ArrowDown until the grid reaches the visible limit and triggers vertical scrolling

4. After the scroll happens:

   • Arrow key events (ArrowDown, ArrowUp, etc.) stop triggering in the gridKeydown handler

5. Verify that:

   • Other keys like Enter still work correctly
   • The issue persists even if you click a cell again to restore focus

Actual Result

Arrow keys (ArrowDown, ArrowUp, ArrowLeft, ArrowRight) stop working for navigation within the grid after scrolling occurs.

Expected Result

It is expected that navigation using arrow keys continues to work correctly even after scrolling occurs.
