I’ve noticed two problems so far with the Beta4. Sorry if they have already been mentionned before but I didn’t find anything related in the forum.
it has something to do with:
( "fetch" in window ) || document.write( "<script src="/wp/wp-includes/js/dist/vendor/wp-polyfill-fetch.min.js?ver=3.0.0"></scr" + "ipt>" );( document.contains ) || document.write( "<script src="/wp/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 src="/wp/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 src="/wp/wp-includes/js/dist/vendor/wp-polyfill-element-closest.min.js?ver=2.0.2"></scr" + "ipt>" );
For some reasons (maybe you are using eslint?), the single quotes are changed to double quotes by the plugin and this probably cause issues.
Thank you for letting me know when it is fixed.
Keep up the good work!
