The members concern sanitizing Matrix outbound markdown output: one issue reports raw HTML and javascript: links surviving in formatted_body, and two pull requests address sanitizing library HTML output and rejecting entity-encoded URL schemes in link handling. Their titles indicate a shared theme, but they do not confirm what the changes accomplish.
