In Form Builder, the rule needs to be duplicated for every control
                            The grid still takes space on the page, even if the controls don't show
                    -->
                    <xf:group ref=".[mailing-address-different = 'true']">
                        <fr:grid>
                            <xh:tr>
                                <xh:td>
                                    <xf:input id="mailing-street-number-control" class="fr-width-5em"
