Row sequence corrupted when reordering a row on a filtered table and pressing Ctrl-z

[THemming]

We've noticed that if you filter a table and drag a row, but press Ctrl-z whilst doing so, it corrupts the row sequence or at least the rendering of it.

Pressing Ctrl-z whilst dragging a row changes the search input (basically calling undo on the input). When dropping a row into a new position the table ends up with duplicate values in the sequence column.

Test case

• Go to example: https://datatables.net/extensions/rowreorder/examples/initialisation/restrictedOrdering.html
• Enter the search text: 85
• Drag row 20 down a couple of places and keep the mouse down
• Press Ctrl-z once
• Release the mouse, dropping the row into the new position

Expected: The row should be in the new position.
Actual: The row has not moved and the sequence column contains a duplicate value of 20.

Thanks for letting me know about this. I'd never have found that one myself!

I'm not sure what the best way to handle this is to be honest. I'll come back to it when I have the opertunity to focus on it a little more and can dedicate some time to it. Leaving open until then.
