[BUG] (expo) EPUB font size changing on it's own

[skridofly]

Description of the Bug

Tabing back into the application, reentering the current book or highlighting a text section sometimes leads to changed font size. This leads to jump ahead to a different page depending on the size change and previous position.

Expected Behavior

The size should consistently be at the set size no matter what

Steps To Reproduce

1. Read a book
2. Be unlucky
3. Reenter book
4. Observe changed position

New Way since latest update:

1. Open Book
2. Turn first page
3. Observe resizing

This only happens on the first on application start. Afterwards it renders the epub on a different font size, but insta rerenders on the proper one.

This has now also happened in the middle of reading with no update given, aside from turning a page after which it took 2 or so second

Edit: It is consistently happening when turning the first page. For reference I am on Font Size 15.5, but it also happens on 16

Edit 2: It does not happen with the offline Reader.
