Description of the bug

It is similar/related to squidfunk/mkdocs-material#7734 which resulted in this fix

The issue is that the text inside h5 headers (class names, function names) is converted to uppercase.

Since there is a fix already in the mkdocs-material itself, which disables this uppercase formatting inside h5.code CSS class, maybe all the class/function names should have the .code class?

To Reproduce

Enable the show_submodules option and have a nested submodules structure, so h5 header will be created for class/function.

Like :

1. Declare in mkdocs.yml

plugins:
  - mkdocstrings:
      default_handler: python
      handlers:
        python:
          options:
            show_submodules: true

2. Define a class like mypackage.exceptions.account_errors.AccountNotFoundError

Expected behavior

The class names (and function names) will be the same as in the python code. (so AccountNotFoundError and not ACCOUNTNOTFOUNDERROR)

Environment information

• cpython 3.12.3
• mkdocs 1.6.1
• mkdocstrings-python 1.16.10
• mkdocs-material 9.6.12

Additional context

I think it is related to: squidfunk/mkdocs-material#1522 and squidfunk/mkdocs-material#7734, which resulted in this fix

The workaround seems to be:

h5 .doc-object-name {
  text-transform: none;
}

defined in the extra.css
