HTML -> ICML produced invalid result

[samatcolumn]

Explain the problem.

I reproduced this on the https://pandoc.org/try/ site with html5 -> icml conversion and the "standalone" option checked.

The input and output are here (too big for the comment body);
https://gist.github.com/samatcolumn/d2edc51eb559c10a1d2c02328a1395d1

The error is specifically in this line of the output:

      <ParagraphStyle Self="ParagraphStyle/TablePar &gt; RightAlign &gt; LeftAlign" Name="TablePar &gt; RightAlign &gt; LeftAlign" LeftIndent="0" Justification="LeftAlign" Justification="RightAlign">

The Justification property is specified twice, which makes the ICML (XML, really) invalid.

Pandoc version?

All versions (and specifically, whatever version is online)

Can you give a more minimal test case or at least identify the line number of that line?

[samatcolumn]

Wow @jgm you fixed it before I even had a chance to provide a more minimal repro, thank you as always!

[samatcolumn]

Fwiw, this is the most minimal repro I could come up with this morning:

html

<div custom-style="LeftAlign">
  <table>
    <tbody>
      <tr>
        <td><div custom-style="RightAlign">Hello</div></td>
      </tr>
    </tbody>
  </table>
</div>
