When the embedded document has the same origin as the main page, it is strongly discouraged to use both allow-scripts and allow-same-origin at the same time, as that allows the embedded document to programmatically remove the sandbox attribute. Although it is accepted, this case is no more secure than not using the sandbox attribute.

        var parent = document.currentScript.parentElement;
        var iframe = document.createElement ('iframe');
