Grid stuck when using keyboard navigation

[youngvan]

Hi

When using the keyboard to move between grid cells and came to the left edge (which contains row numbers), the page with grid stuck until you forcefully close it. This begins after migration to v5.1.0 from v3.3.2. 
With v3.3.2, if you click a left arrow on a keyboard when the left cell is selected, the selection just moves to the right cell of an upper row.

Please check the custom code if any written in key* ( down, up, etc) events.

Or share a jsfiddle of the issue.

When you came to the left edge using arrows on the keyboard, the page stuck
But if you remove "hidden":true from the first column - all works fine
