[agoldenbaum]

Steps to Reproduce

1. Run the attached sample project.
2. Click on a cell in the Age field and edit the value. Remember this cell.
3. Click on the Add Row button.
4. Select any cell from the newly added row.
5. Use Shift+Tab to move the focus to the previously edited Age cell in step 2.
6. Press Enter to attempt editing the cell.
7. Optional Click the same cell.

Result
Cell does not go into edit mode from the Enter key, but clicking it puts it into edit mode normally.

Expected Result
Cell should go into edit mode on the press of the Enter key because of the setting on the grid: enterBehavior={EnterKeyBehaviors.Edit}
