Web Forms :: LinkButton A:visited Style Not Showing In IE8?

In IE8 after clicking a LinkButton, I am unable to get the button to display it's a:visited style. I want the LinkButton to show in a different color to show that it has been clicked, like a Hyperlink does.I read on another forum that the browser needs to have the Href value saved in it's history, but this doesn't seem to work for a linkbutton. It works for a HyperLink control, but not a LinkButton. I'm wondering if this is a known bug with the LinkButton. In the example below I have a linkbutton in a GridView, but I can't get it to work for any LinkButtons:

<asp:LinkButton
ID="lbtnEdit"
CommandName="Edit"
CommandArgument='<%# DataBinder.Eval(Container.DataItem, "pattern_ID") %>'
runat="server"
Text="<%&#36; Resources:Resource, Edit %>"></asp:LinkButton>

Here is what if renders as in the ViewSource:

<a id="ctl00_cphMain_gvWbpatternlist_ctl25_lbtnEdit"
href="javascript:__doPostBack('ctl00$cphMain$gvMyGridView$ctl25$lbtnEdit','')">Edit</a>
