Why HTML5 deprecated percentage coords definition in the area tag?

I'm not the only one who see this as a de-improvement (he see it as a Bug):

http://home.comcast.net/~urbanjost/IMG/resizeimg4.html

Now I've to say, i don't like <area> and <map> and i now is obsolete stuff,
so i'm happy if they will be deprecated soon, but I think we need some pure
DOM solution to draw polygons.

In my case, I'm trying to implement a pure DOM  clickable pie-slices (not
with Canvas or SVG just because it need to be a cross browser app).

So I did it in the easiest way: images for slices and the old fashioned
<area> tag....

but... i've fluid images with size in percentage.

Best regards,
Stefano.
