Add support for the vertical layout EPUB format books
Currently viewing vertical layout ebooks in Zotero has several issues: I can neither scroll nor jump to next page, it jumps to next section, also reading the remaining content of a page is impossible. Additionally, some text appears outside the viewer borders.

Thank you so much for the hard work. I hope this bug can be fixed soon and then I could start using the wonderful reader.
