Description

What's wrong:
When user is editing a cell and the underlying grid data array is updated by adding or removing rows, the edit mode is shifted to incorrect cell.

How to repeat:
See Plunker

Expected behavior:
a: Stop edit mode when number of rows is changed while a cell is in edit mode.
(potentially easier to implement(?), but not ideal UX) b: Keep edit mode on correct cell.

Research direction
Reproduce the issue using the provided Plunker link. Investigate the UI Grid source code, particularly the cell edit mode logic and how it handles changes to the grid data array. Look for any existing mechanisms to cancel edit mode when row count changes, and consider implementing either option a (stop edit mode) or option b (keep correct cell). The plunker demonstrates the bug clearly; focus on the event handlers that update the data array and the grid's internal edit state.
