This script conflicts with the Google Hit Hider script. The author of it suggests changing the line 39 from

gs[i].innerHTML = `<span style="position: absolute; left: -20px; top: 4px;">${i+1}</span>${gs[i].innerHTML}`;

to

gs[i].insertAdjacentHTML('afterbegin', `<span style="position: absolute; left: -20px; top: 4px;">${i+1}</span>`);
