The original mail consists of two base64-encoded blobs of content. If you "base64 -d" the second blob, it's not even a fully proper HTML document. There are no initial <html> headers or anything. It simply begins with some lowercase English text, then <br><div> and another line of text, </div><div> and a third line, and so on. How your HTML-based mail user agent responds to that will depend on the decisions made by its authors.
