Using HTML in jQuery UI autocomplete

Before jQuery UI 1.8.4 I could use HTML in the JSON array I built to work with an autocomplete.

I was able to do something like:

$row_array['label'] = '<span style="color: red; font-family: courier;">User, Name</span>';

That would show up as red text in the drop down.

As of 1.8.4 that does not work. I found http://dev.jqueryui.com/ticket/5275 which tells me to use the custom HTML example here which I have had no luck with.

How can I go about getting HTML to show up in the suggestion?

My jQuery is:

<script type="text/javascript">
    $(function() {
        $("#findUserIdDisplay").autocomplete({
            source: "ui_autocomplete_users_withuname.php",
            minLength: 2,
            select: function(event, ui) {
                $('#findUserId').val(ui.item.id);
            }
        });
    });
</script>

My JSON array includes HTML like the following:

[{"label":"<span style="color: red";>User, Name</span>","value":"User, Name","id":"10"}]
