背景出现在IE8的Fieldset边界之外

Question

I have been working on doing CSS hacks to make things work in Internet explorer 7 and 8 that normally work in Chrome/Firefox. I have fixed most of the issues but I can't figure this one out and I was hoping for some help.

Here is how my login box looks normally:

And here is how it looks in IE 8:

Id like to get them looking the same, but at a minimum fix how the color goes past the border. Any thoughts?

Edit:

here is the html/server control that renders the login box:

<form>
<fieldset style="width: 20" align="center" id="login_border">
    <legend id="login_box">Login</legend>
    <asp:Login ID="Login1" runat="server" 
        TitleText="">
    </asp:Login>
</fieldset>
</form>

Here is the CSS:

#login_border 
{
    Border: 0.25em black solid; 
    margin-left: 1em; 
    padding: 0.2em 0.8em;
    background-color: #fdbe12;
    position: fixed;
    top: 50%;
    left: 50%;
    margin-top: -100px;
    margin-left: -142px;
}

#login_box 
{
    Border: 0.1em black solid; 
    margin-left: 1em; 
    padding: 0.2em 0.8em;
    background-color: White;
    font-size: 1.5em;
}

.login 
{
    font-size: 1.1em;
    font-weight: bold; 
}

You can try to give negative margin-top to legend and this will get fixed.

*margin-top:-22px;   //for IE7
margin-top:-22px\0/; //for IE8, Note `\0/` characters here.
