When reading a long epub Zotero does remember reading position. But it doesn't seem to remember the exact readion position. When re-opening the file or when re-opening zotero after a few days and then open that file, the file is opened but position is 1 or two pages before the last reading position.

This is reliably reproduced on an android phone. I specifically highlighted a sentence where I left when reading. Re-opening zotero opens the epub two pages before the page with the highlight.

Is this expected behavior and could it be tweaked to remember exact reading position so users don't have to swipe around to find the actual last reading position?
