Embedded notebook cells do not show source references in book format

Bug description

The embedded notebook cell feature does not produce source links to the notebook when used in book format. I would have expected this feature to work in book format, too - at a minimum, when the book output format is HTML (though it may apply to other formats, too, as long as the notebook is included in the book somewhere).

I can see situations where the book includes code snippets along the way with the entire notebook available in the appendix, and having the ability to click through to the entire notebook would be awesome.

This does not seem to be controlled by notebook-links or notebook-view settings - changing them has no impact.

Steps to reproduce

Embed a cell from a notebook foo.ipynb into a document using shortcode:

{{< embed foo.ipynb#foo >}}

Expected behavior

The rendered page should include both the content of the notebook cell as well as a source reference to it.

Actual behavior

The rendered page only includes the content of the notebook cell.

Use the embed foo.ipynb#foo shortcode as the reproduction entry point and compare its behavior in an HTML book while checking whether notebook-links or notebook-view affects the result. Done means the rendered cell includes a source reference to the notebook when that notebook is included in the book.
