It is written that Firefox supports alt attribute in <area> element. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/area

But what does it mean? alt attribute in element is shown when the image is unavailable. But alt attribute in <area> element is not shown even if the image is unavailable. So I want to know when it will be used. And how Firefox supports alt attribute in <area> element.

Best regards,
