Mode-line face conflict with nano-theme

[albreche]

Step to reproduce, in dark mode:

1. open a .el file (which default to book-mode) . Mode line face is as wanted, empty.
2. then open an info file (eg: elisp manual) which is opened in info mode
   Then modeline of the book-mode window as a nano-faded background.

I do not get the problem. How did you make book mode the default? Can you post screenshots?

[albreche]

I setup book-mode with use-package, as follow :

 (use-package book-mode
  :straight (book-mode :type git :host github :repo "rougier/book-mode.git"
                      :local-repo "~/src/book-mode"
                      :fork (:host github  :repo "albreche/book-mode"))
  :hook (org-mode . book-mode))

below a screenshot.

Oh, I think the problem comes from the mode-line-inactive face. As a quick test, can you make it yellow (for example) to check if this is the origin ?
