Any way to prevent "deselection" of highlighted text?

Highlight some text on this webpage, then click basically anywhere on the document. Your selection will disappear.

Is there a way to prevent this behavior when the user clicks on a specific element, either by CSS or Javascript?

E.g.:

var element = document.getElementById("foo");
foo.onclick = function(e){
   //some magic here that prevents deselection from occuring
}

or

foo.style.preventDeselect = "true";

Edit: Perhaps I could store the selection, then after "mouseclick" restore the selection? Is there a way to store aselection, and then reselect it?

Thanks!
