Using HTML in a Dialog’s title in jQuery UI 1.10

This will override the function used when setting jQuery UI dialog titles, allowing it to contain HTML.

$.widget("ui.dialog", $.extend({}, $.ui.dialog.prototype, {
    _title: function(title) {
        if (!this.options.title ) {
            title.html(" ");
        } else {
            title.html(this.options.title);
        }
    }
}));
