Description

When backend validation is involved, canceling the cell commit (event.cancel = true) and then programmatically exiting edit mode (cell.editMode = false) causes keyboard navigation to stop. After this flow, the cell exits edit mode, but arrow keys no longer navigate between cells.

2. Edit any cell in the grid.
3. Press Enter the handler cancels the commit (event.cancel = true) and uses a timeout to set cell.editMode = false.
4. Try navigating with Left/Right arrow keys.

Result

After canceling the edit and exiting edit mode, arrow keys no longer work. Keyboard navigation is blocked.

Expected result

After exiting edit mode, keyboard navigation should continue to work normally, including arrows.
