blank sites when convert azw to epub

[Camelot]

When convert a Kindle ebook from the german publisher "Forever" to epub, all sites are blank.

I think the problem is the following from the original stylesheet:

*::footnote-call {
  content: none;
  display: none;
}

After the conversion, all classes have display:none.

I created a small test file and attached the original CSS file.
Convert the test.epub to epub and you can see the problem.

Calibre v3.48
OS: Siduction (Debian/sid)

You might try setting up a transform styles rule in the conversion--Look and feel, Transform styles tab. I tried "if the property content is none remove the property" and "if the property display is none change the value to block". That worked for the test file, but it might be more complicated on the real thing. I didn't try and understand that whole messy css.

If I had a book with that "wrong.css" and wanted to make it readable for me, I'd rip out all that nonsense and use my own css file anyway, in the editor.

It works with the rule, but I must delete it for other books to be on the safe side:

# If the property display is none
# Remove the property
match_type: is
action_data: 
action: remove
query: none
property: display

But is that a converting bug from Calibre or not?

edit: wrong.css is not the original file name

I would not call it a bug at all. Given the infinite array of coding garbage available in e-books, combined with different users expectations of what makes a "good" conversion, and the tools provided to deal with exceptional situations like this...what would you want? The software should read your mind and do it your way?
