Add a static regression for the shared action-buttons stylesheet.

 - Keep message DOM helpers compatible with extension points that modify rendered messages.
 - Sanitize or safely render model/user-provided content through shared rendering paths.
 - Avoid layout shifts that break long-running message streaming.
