I'd also find it confusing, because it seems like that means if you zoom in, the scrollbar would be for the current page, but then if you zoom out, it would be for the entire document. Is that how other viewers actually work, or is it more elaborate than that?
Obviously this isn't a model interaction with an open source project either way. Although I don't think how they responded was ideal, I don't think I would've enjoyed communicating with you on that thread if I were the maintainer, either. Nobody's perfect, but all in all, I'd hope you agree that this has thusfar not been very productive on either side.
