pip show <package_name> error with `Autor`, `Author-email` and `Home-page`

Description

When Im using pip show with pip show python-docx package (or any one else):

$ pip show python-docx
Name: python-docx
Version: 1.1.0
Summary: Create, read, and update Microsoft Word .docx files.
Home-page:
Author:
Author-email: Steve Canny <stcanny@gmail.com>
License: MIT

Were can to see empty Author and Home-page.
But: Author-email == Author + email

But at the origin pyproject.toml there are:

[project]
authors = [{name = "Steve Canny", email = "stcanny@gmail.com"}]

[project.urls]
Homepage = "https://github.com/python-openxml/python-docx"

Another strange thing, that the pip show is project.urls.Source, but not project.urls.Homepage

Expected behavior

Python version

OS

Output

Name: python-docx
Version: 1.1.0
Summary: Create, read, and update Microsoft Word .docx files.

Author:
Author-email: Steve Canny stcanny@gmail.com

With respect to labeling, I do not believe this is a bug: pip show python-docx seems to be giving an accurate reporting of the correctly recorded metadata. For an example of prior discussion on this, see pypa/packaging-problems#670 (comment)

The two topics mentioned in this issue are populating Home-page from Project-URL and Author from Author-Email during a pip show call. Happily, the first was discussed in #11221 and addressed in #12569 which has already been accepted! I was unable to easily find a similar effort underway for Author. But even if no such issue exists, then I'm not sure if this should be relabeled and re-framed as such, or if that ought to be done in an issue specifically crafted for it?

Just for completeness, Steve Canny <stcanny@gmail.com> is a valid email value using the optional display name format. Most humans associate the term email to only the foo@domain part, so that’s what we use in pyproject.toml (which is written and read by humans), but the metadata format (written and read by machines) uses the technically more accurate terminology for historical reasons.
