Comment 4 for bug 1918436

Attached can be a more obvious example (sorry it's in Chinese). I opened it with E-book viewer running on macOS Big Sur, and highlights are also not in order.

Please go to the first chapter (「第一章 那邊」) and the second chapter (「第二章 陌生語言」). In the first chapter, there are only two highlights, and they are reversely listed on my machine. In the second chapter, the order of highlights appear to be at random.
