You are correct, we do change the selection in the notes table according to the current page. But it dose not mean the ’note selection’ is equal to the visible notes, it just means that the selection is synchronized. > But not all notes get selected by this implicit scrolling change (especially > in 2 page view), and some are selected before the page they are on is > scrolled into view.

When the selection is for the current page (according to the PDF view), we leave it. Otherwise, we select the first note for or from that page. > There is a bug in this 2-page scrolling (perhaps in PDFView, this is MacOS > 11.3): the current page (even one sided) stops getting updated sometimes, > except on single-view pages (like the first).
