deleteRow confirmation dialog can suppress future deletions

When deleting a row (which I am doing through calling handleDropRow), a confirmation dialog appears.

If I check 'Prevent this page from creating additional dialogs', then on subsequent calls to handleDropRow, the row does not get deleted and there is no indication that a delete was attempted, even after reload of the page.

I have fixed this by using handleConfirmDeleteRow and calling next() to skip the confirmation, which works just fine, but I do not think the ability to prevent row deletions with that checkbox should be the default behavior.

This is using Chrome Version 51.0.2704.103.

Thanks for all the work on this great package!
