Ex Infinite Scroll to Top

The app do the work. I've not checked the performance impact so I cannot say. But for the UX it is great.
Only issue is the collection-list page, where the pagination is hidden but no feature from the app is implemented, causing your website to only display one set of collections corresponding to the first "page". I do have more than 50 collections, thus this page is essential. I added a quick fix using JS script and removing the "display:none" property that that script of the app set. It would be great to add a condition in your js cdn, in order to activate you code only on the pages where we added the script mentioned in your installation guide. Indeed, if I use my paginate component for something else, it will be hidden by your script by default I guess. Other than that, really quick and efficient app.
