[Bug]: Loaded Plugins not shown in Site Health > Info > MU Plugins

[joshuadavidnelson]

Description of the bug

The primary plugins screen shows all the loaded MU plugins, however I would expect the Site Health > Info > Must Use Plugins section does not show the plugins loaded by the MU Loader.

Reproduction instructions

1. Go to Tools > Site Health
2. Navigate to the "Info" tab
3. Expand the 'Must Use plugins' section
4. Plugins listed here do not include those loaded by the MU Loader

Expected behavior

The Site Health > Info > Must Use Plugins section should show the same list as the Plugins > Must Use section, including those loaded by this loader.

Environment info

MU Loader v1.3.1
WP v6.3.1

Relevant log output

No response

Enhanced for the understanding, an example:

Three plugins in the mu-plugins directory:

The plugin page in the admin area:

The site health information miss ONE plugin in this case:

The filter hook plugin_auto_update_debug_string should be the right point to enhance the missing information.
