Pandoc treats <w:highlight w:val="none"/> in docx sources as highlighting

[afontenot]

Explain the problem.

I generated the document test.docx with OnlyOffice by adding a little bit of text, highlighting part of it, and selecting "no fill" for the highlight color. (As an example, this could happen naturally if something was highlighted by accident, and then "no fill" was selected to remove the highlighting.)

Running pandoc -o test.typ test.docx results in the following output:

This is some text.

#highlight[This is some text.]

#highlight[This is some text.]

This seems to be due to the following in the source document:

      <w:r>
        <w:rPr>
          <w:highlight w:val="none"/>
        </w:rPr>
        <w:t xml:space="preserve">This is some text.</w:t>
      </w:r>

I don't observe any issue with the test file when opening it in e.g. LibreOffice.

Pandoc version?

3.7.0.2 (latest)
