Problem description: 
When using CTRL+D to duplicate the contents of the cell above, the cell populates, but then if you press F2 to edit it without moving out of the cell, you are editing an empty cell.  Moving (arrow keys) away from the cell and back again first lets the cell update (?) and the contents are there fine.

Steps to reproduce:
1. Add a value to cell A1 (e.g. type "123" and press Enter).
2. Move to cell A2 and press CTRL+D.  Value should populate to the second cell.
3. Press F2.  Now editing what appears to be a blank cell.

Current behavior:
As above.

Expected behavior:
When pressing F2, I should be editing the value I just duplicated into the second cell.
