A sample DOCX that can be opened in LO, but not Word 2016

Opening the attachment in Word 2016, an error is reported:

<span class="quote">> Word found unreadable content in file.docx. Do you want to recover the contents
> of this document? If you trust the source of this document, click Yes.</span >

followed by

<span class="quote">> Word experienced an error trying to open the file.
> Try these suggestions:
> ...</span >

Opening it in LO succeeds; saving it again as DOCX generates the same problem
in Word.
