964058 - image map links not displayed or operable when img src broken

Status: NEW

(Core :: Layout, defect, P4)

Description

[steve faulkner]

When an img has  associated active areas via usemap and the img src is broken the alt text of the area elements is not displayed so links become mystery meat.

reproduce:
open https://dl.dropboxusercontent.com/u/377471/image-map.html

contains an img with associated <area> elements. As the img src is incorrect none of the active areas (links) are operable or visible i.e. no fallback.

expected behaviour:

the area elements are displayed on the page as links with the link text as per the alt attribute text of the area elements.

It's worth pointing out (once again) that unless the image was loaded properly, the map and its area elements are completely useless. They cannot be focused by script, they cannot be tabbed to, they cannot be clicked on.

Since area elements cannot by styled themselves and they're not easily accessible via the img element in CSS, it is not possible to work around this problem without employing JavaScript.
