 * replaced:
    `for (var r = [], l = _altLayouts.default[JSON.parse(e.attrs.tpl).
   length + “-sections”], n = 0; n < l.length; n++)`
 * with:
 *     ```
       var l = 1;
                   if (typeof _altLayouts.default[JSON.parse(e.attrs.tpl).length + "-sections"] !== 'undefined')
                       l = _altLayouts.default[JSON.parse(e.attrs.tpl).length + "-sections"];
                   for (var r = [], n = 0; n < l.length; n++) r.push(responsiveLayoutElement(l[n], n, t));
       ```
   
 * seems to be working, but not sure if there are unintended consequences?
