I believe it happens here. I'm not experienced with the codebase, so I'm wondering why it would hardcoded like this. Is there some weird bug that happens when not temporarily changing to page view? Do we change to page view to get page counts or something?

It is necessary for exporting to graphics, so I think that is the reason that it's there. But indeed it doesn't make a lot of sense for audio or midi export.
