[BUG] Value being cleared out even though it should have retained the value since there's no changes made

[Unidraga]

Using the demo given, under the "Ajax country request" column.

When you type 'cana' and hit Tab key, it'll select 'Canada' and move over the right, which is the 'Capital slow request with spinner' column.

Go back to the cell that says 'Canada' and double click on it.
It'll show the cursor that's waiting for input.
Now click on any other cell.
The cell 'Canada' will be cleared out.

The expected behavior is that it should retain whatever was in the cell instead of clearing out the cell.

Take 'Price' column for example, the value in the cell retains after following the steps detailed above.
