Bookworm showing number instead of correct heading level formatting in epub files

[DraganRatkovich]

I know again that the title of the question is a little tricky when it gets read, but I'll try to explain the specific problem in as much detail as possible.

Describe the Problem

When opening an epub file that contains heading level 1 formatting to list book chapters, Bookworm, sometimes, only shows numbers instead of heading formatting.
To be more precise, in the places, where the screen reader should say "Heading level 1" and the text of the chapter, it only says 1.
This problem occurs periodically and after a while, it resolves itself again. Sometimes, the documents that I opened and were properly formatted and also displayed without errors in Bookworm, after a while, these documents also did not display the heading formatting correctly and only displayed the number instead of the heading formatting.
During a bug where Bookworm only shows a number instead of the correct formatting, the H also doesn't move to the correct heading and there is no heading in the document, but the table of contents shows the chapters without problems and when you click any of the chapters, the Bookworm jumps to the right chapter, but again, there is no heading formatting, and only the number 1 is displayed.
This issue only occurs with epub files, a Word document, that is also formatted with a heading level 1 displays without problems.

To Reproduce

Actually, not sure because this problem only occurs intermittently, but just open the epub file and see the result. There is nothing special to say, because, perhaps, the problem does not even arise for someone.

Expected behavior

Bookworm should display heading formatting without errors in epub files, just like in Word documents.

Desktop (please complete the following information):

• OS: Windows 10;
• Bookworm version: latest, downloaded from AppVeyor;
• Settings changed: none
