I can just hide the element in CSS anyway, it just doesn't look neat. I suppose you could inject the CSS if you need to?
<style>#flarum-content,.App-content span:nth-of-type(2) .container{display:none}</style>
You could inject that into the header to do it. The problem with styling <noscript> tags is that Firefox removes them entirely and replaces them with span elements, whereas Chrome-based browsers will allow you to select it hence why you need two different rules to select the element!
