Temporarily not in edit mode after changing editable twice in a row

[TomoyaWashio]

If I change IgrColumn's editable from button to false while editing a cell, cell editing is canceled, but if I change it back to true and double click on the same cell, it does not go into edit mode.
*Once the other cell is put into edit mode, the problem is resolved.

The reproduction procedure is as follows

1. Activate editing with the Edit ON button.
2. Double-click any cell in Column1 to start editing.
3. Consecutively click Edit OFF button → Edit ON button while the cell is being edited (cell editing is canceled).
4. Double-click the cell in step 2→Cannot start editing.

Here is a sample to reproduce the issue.
