wp-polyfill error

Hello,

when I activate the plugin, it will break the site by adding
async='async' to every script line.
Since WordPress uses Gutenberg officially with Version 5.0 the wp-polyfills-*-min.js are added in a special way.

Code:

<script type='text/javascript'>
( 'fetch' in window ) || document.write( '<script async='async' src="https://example.com/wp-includes/js/dist/vendor/wp-polyfill-fetch.min.js?ver=3.0.0"></scr' + 'ipt>' );( document.contains ) || document.write( '<script async='async' src="https://example.com/wp-includes/js/dist/vendor/wp-polyfill-node-contains.min.js?ver=3.26.0-0"></scr' + 'ipt>' );( window.FormData && window.FormData.prototype.keys ) || document.write( '<script async='async' src="https://example.com/wp-includes/js/dist/vendor/wp-polyfill-formdata.min.js?ver=3.0.12"></scr' + 'ipt>' );( Element.prototype.matches && Element.prototype.closest ) || document.write( '<script async='async' src="https://example.com/wp-includes/js/dist/vendor/wp-polyfill-element-closest.min.js?ver=2.0.2"></scr' + 'ipt>' );
</script>

Error:

Uncaught SyntaxError: missing ) after argument list

Kind regards.
