Here's a bookmarklet which fixes that:

  javascript:(function(){const e=['wheel','mousewheel','DOMMouseScroll','touchmove'];e.forEach(e=>{window.addEventListener(e,function(e){e.stopPropagation()},{capture:true,passive:true})});const t=e=>{if(!e)return;e.style.setProperty('overflow','auto','important');e.style.setProperty('overflow-y','auto','important');e.style.setProperty('overflow-x','visible','important');e.style.setProperty('scroll-behavior','auto','important');e.style.setProperty('position','static','important')};t(document.documentElement);t(document.body);const o=document.createElement('style');o.innerHTML='html, body { overflow: auto !important; overflow-y: auto !important; scroll-behavior: auto !important; position: static !important; height: auto !important; } ::-webkit-scrollbar { width: 12px !important; display: block !important; }';document.head.appendChild(o);})();
