Form fields do not have duplicate labels
Ensures form field does not have multiple labels.
Assigning multiple labels to the same form field can cause problems for some combinations of screen readers and browsers, and the results are inconsistent from one combination to the next. Some combinations will read the first label. Some will read the last label. Others will read both labels.
