We need to be aware of any element referenced using the
aria-labelledby/aria-describedby labeling on form fields.
That elemenb's value is announced to screen reader users regardless of
its visibility.
display: none/
visibility: hidden/
aria-hidden="true"
are all ignored when calculating the accessible name per the ARIA spec.
So that is one situation where hidden content is announced to screen readers.
