Standard EBooks Adds (kepub imports as epub)

When I add a kepub from Standard Ebooks, it shows up as an epub instead of as a kepub.

Also, when I add the advanced epub from Standard Ebooks, no cover comes through.

Any ideas?

Here's an example to try out:

I'm using 8.12.

StandardEBooks code is atrocious. Try here to see if the same eBooks are available.

I usually get my public domain books from either Project Gutenberg or the library. However, I do like how they will compile short stories by authors into Short Fiction books. And there are some books they have that I can't find either at Project Gutenberg or the library.

What code is atrocious?

Using the book you linked...

The downloaded kepub is has filename & extension
Code:
h-p-lovecraft_the-case-of-charles-dexter-ward.kepub.epub
If you import that file into your calibre library as-is, calibre will see it as an epub because calibre only sees the .epub file extension. If you want calibre to recognise it as a kepub then rename the file to the following before importing
Code:
h-p-lovecraft_the-case-of-charles-dexter-ward.kepub

I have some follow-up questions.

On my Kobo, if I look at the file extension, it shows as kepub.epub. When I look at my Calibre library, I see only kepub.

Since it appears that Calibre will treat the kepub.epub file extension as epub, what happens when I convert that kepub to an epub or kepub? I'm looking at the results in the viewer, and they still look okay. But I'm expecting something to not work right.

Is the best practice now if I download a file with a kepub.epub extension to rename it?

What would have to change in Calibre to treat the extension kepub.epub as a kepub?

The code used for the eBooks from StandardEBooks is atrocious. It's why there are problems with it. It's why it won't work as an ePub with a Kobo. I don't know why they insist on using code that they don't need to use. It's awful.

The device driver handles the rename from .kepub to .kepub.epub when the book is transferred to the Kobo.

The use of a single extension to identify ebook type is just how it is and I really doubt kovid would ever consider a change

Calibre can view either. KEPB just has additional markup that Calibre ignores.
