Bug Report

When a navigatable Kendo UI Grid is configured with a stacked dataLayoutMode and is in an inline edit mode, using the arrow keys fails to operate as expected for the editor.

Reproducible

1. Go to this Progress Kendo UI Dojo.
2. Edit any line and get into text field or numeric field.
3. Use the arrow keys to edit the component, such as up/down for numeric change or left/right to move cursor in textbox

Current Behavior

The left and right arrow keys do not appear to function. The up and down arrows move to the next rows.

Environment
