Robert Murphy commented on WICKET-6753:
---------------------------------------
When ModalWindow is displaying an iframe updateTitle is setting the aria-label.
I trust your judgement. The important part is that non-id content not be placed
in the aria-labelledby and that aria-labelledby be omitted when there isn't an
id or if the id refers to an element that has no text.

> aria-labelledby attribute value should be the id of an element containing the
> label for the element with the aria-labelledby attribute. aria-label
> attribute value contains the label for the element with the aria-label
> attribute. We got sued for ADA Compliance Errors. The lawsuit cites the
> Errors and Alerts generated by the WAVE tool (by WebAIM).
> The bug causes WAVE Error Broken ARIA reference.
> The fix:
> Instead of copying the title to the aria-labelledby attribute, don't use
> aria-labelledby at all and instead copy the title to the aria-label attribute.
