Bandsnatch only fetches first 20 hidden collection items

[jackkinsey]

I have a decent number (~80) of hidden items in my collection. I've noticed that some but not all of these are downloaded by Bandsnatch.

If I open my collection, click hidden items in the top right, then (after the autoscroll down) scroll up and click view all items, and finally scroll to the bottom of the page again, the list will show all unhidden collection items, but only the first 20 hidden items. I assume this is relevant somehow.

I've worked around this by unhiding, downloading, and rehiding the relevant collection items, but it would be nice to be able to avoid doing that.
