No data until last page

I can not get any scrapped data until the pagination reaches the last page. If I close the scrapping window halfway I can not get anything. Is it a bug or feature? If I only need first 100 pages out of thousands, how can I do that?

@trainspotting Hello, that most likely happens because the 'pagination' is based on a click selector.
