I have ‘Saved As’ your 22.docx document to HTML by using MS Word 2016 (see msw-2016.zip (771 Bytes)). You can see even MS Word 2016 exports font-size:11.0pt; to that Paragraph (see p.MsoNormal style definition). So, this seems to be an expected behavior. If we can help you with anything else, please feel free to ask.
