AXImageMapLink::elementRect() has code path to deal with the case that a map is not referenced by any image and the result seems incorrect.

Normally maps and areas are invisible by themselves because their default style is "display: inline; width: 0; height: 0". If a map is referenced by an image, it creates areas in the image which respond to user interactions.

If a map and its areas are forced to be visible (e.g. using "display: block; width: 100px; height: 100px", regardless of whether the map is referenced by any image, the map and areas are visible and respond to user interaction by themselves. If the map is not referenced by any image, the map and areas should be treated just like normal blocks ignoring the shapes defined in the areas. Calling area->computeRect(map->layoutObject()) seems incorrect.
