::selection pseudo-element and text-decoration

See:
http://www.w3.org/TR/css3-selectors/#UIfragments

So you can use color, cursor, background and outline for the ::selection 
pseudo-element.

But I'm missing the text-decoration property. Why is that? I see no harm 
in supporting it.

If I have a style with text-decoration:blink, it would be nice if I 
could alter it back to a normal text-decoration, e.g.
::selection{ text-decoration:none;}

Kind regards,
