Themes

I found this in moodle/lib/editor/tinymce/lib,php...which makes me suspect there is a bug in there somewhere!

        if (!empty($options['legacy']) or !empty($options['noclean']) or !empty($options['trusted'])) {
            // now deal somehow with non-standard tags, people scream when we do not make moodle code xtml strict,
            // but they scream even more when we strip all tags that are not strict :-(
            $params['valid_elements'] = 'script[src|type],*[*]'; // for some reason the *[*] does not inlcude javascript src attribute MDL-25836
            $params['invalid_elements'] = '';
        }
        // Add unique moodle elements - unfortunately we have to decide if these are SPANs or DIVs.
        $params['extended_valid_elements'] = 'nolink,tex,algebra,lang[lang]';
        $params['custom_elements'] = 'nolink,~tex,~algebra,lang';

        //Add onblur event for client side text validation
        if (!empty($options['required'])) {
            $params['init_instance_callback'] = 'M.editor_tinymce.onblur_event';
        }

        // Allow plugins to adjust parameters.
        editor_tinymce_plugin::all_update_init_params($params, $context, $options);

        // Remove temporary parameters.
        unset($params['moodle_config']);

        return $params;
    }
