Description

The TODO comment in the sanitize_html_class() function suggests expanding its support to include the full range of characters that a class attribute can contain. Currently, the function only allows alphanumeric characters, hyphens, and underscores.

However, updating the function to support a broader set of characters may break some existing tests.

### Summary

Currently, the function only permits alphanumeric characters, hyphens, and underscores. The change will allow a broader set of characters, aligning with the HTML specification for class attributes.
