Autocomplete input in form with jQuery Unobtrusive Validation prevents form from submitting

I have a form with a required (`data-val-required`) autocomplete field. When the field contains a value and I attempt to submit the form, jQuery validation fails on the cloned field (`tt-hint`) because it copied the `data-val` attributes.

I suggest removing `data-val=true` from the cloned field. Let me know if you need an example.
