Navigation In Grid through KeyDown Misbehave in Virtualization with FrozenColumn

Dear Sir/Mam

I would like to tell you that when we use the frozen column with virtualization in the grid, there is a problem in navigation by continuously pressing the arrow keys.

You have fixed many bug but because of this problem we are not able to update your new versions.

We are sending you videos of With Problem and Without problem.


In this example just enableVirtualization = true ​then navigate through LongPressing ArrowDown And ArrowUp

Please give us any alternate or fix this issue or urgent basis.

Thanks with Regards

Nagendra  Gupta
