Image lazy loading with scrolling not fully working

So I am using the scroller feature which is really cool, but unfortunately I am not able to retrieve the full list of images for each product. I think it has to do with lazy loading but I have no way to debug or change it.

This doesn't solve it. If you try yo run this and export the data, you will see that some rows will have the "image" column blank.

You should be able to replicate this with both my and your script
