Preface rendering error in the EPUB file (version 2020-10-28)
Hello, I'm just a reader, but when I first started reading the EPUB file (the cover has the date "2020-10-28"), I saw this "error" in the preface (see image):
I am reading using the Books app on my macOS 10.14.5.
I'd like to note that this error exists in the EPUB file but not in the PDF file of the same date.
The error specifically specifies "Below is a rendering of the page up to the first error", which means that what you can already see does not have errors, however the error lies somewhere in the rest of the preface that isn't shown on my EPUB file. So the error is somewhere after the Cover Image, but still in the preface.
Also, the next page on my EPUB file is immediately Chapter 1, "1 Introduction", so there's nothing left of the preface on my EPUB file.
I hope the devs can fix this. Thanks!
