Issues with the "Load more comments" button in guides

[benoit74]

Two issues have been identified :

• When there is multiple steps with the "load more comments" button, only the first one is working properly
• Sometimes the "load more comments" button is displayed but there is no more comments to display (cf. step 20 of guide 95634- https://fr.ifixit.com/Tutoriel/Remplacement+du+bloc+d'alimentation+de+l'iMac+Intel+215-Inch+Retina+4K+(2017)/95634)
