CSS3 ::selection selector not working properly on anchor tags

I am using the CSS3 ::section Selector like this

::selection{
    color:red;
    background-color:pink;

}
::-moz-selection {
    color:red;
    background-color:pink;

}

So when some element is selected it should change its color to red and the background to pink.

It works as expected for everything other than the Anchor tag <a>.

When an anchor text is selected, it applies the style to the link text but not on the line beneath the anchor text.

So how can we apply the style to the underline also?

PS: Browsers tested: chrome 31 and firefox 25.0.1
