mapcss area selector matches open lines

[francois.lacombe]

Hi,

It seems that the mapcss area type selector matches open lines on JOSM.

Use this simple piece of mapcss :

area[test="ok"]{
        fill-color:"#31A500";
        text-color:"#00DE00";
}

and draw an open line with test=ok and the space between its nodes is filled.

That doesn't sound right against the definition given here : ​http://wiki.openstreetmap.org/wiki/MapCSS/0.2#Types

Am I wrong ?
