Pandoc 3.1.3 / OSX 12.6.5 / HomeBrew version

this is my command line that causes the bug :
pandoc -f docx+styles -t dokuwiki juste_listes.docx -o juste_liste.txt

juste_liste.docx is a document with just one unordered list in it.

If I use this command line pandoc -f docx -t dokuwiki juste_listes.docx -o juste_liste.txt, without +styles, I get this result :

  * Liste 1
  * liste 2
  * liste 3
    * liste 3a
    * liste 3b
    * liste 3c
  * liste 4

If I add +styles here is what I get :

<HTML><ul></HTML>
<HTML><li></HTML><HTML><p></HTML>Liste 1<HTML></p></HTML>
<HTML></li></HTML>
<HTML><li></HTML><HTML><p></HTML>liste 2<HTML></p></HTML>
<HTML></li></HTML>
<HTML><li></HTML><HTML><p></HTML>liste 3<HTML></p></HTML>

<HTML><ul></HTML>
<HTML><li></HTML><HTML><p></HTML>liste 3a<HTML></p></HTML>
<HTML></li></HTML>
<HTML><li></HTML><HTML><p></HTML>liste 3b<HTML></p></HTML>
<HTML></li></HTML>
<HTML><li></HTML><HTML><p></HTML>liste 3c<HTML></p></HTML>
<HTML></li></HTML><HTML></ul></HTML>
<HTML></li></HTML>
<HTML><li></HTML><HTML><p></HTML>liste 4<HTML></p></HTML>
<HTML></li></HTML><HTML></ul></HTML>

The first command, without +styles gives me syntactically correct dokuwiki format.

I need the +styles extension to retain custom styles convert them with a lua filter and later parse them with a dokuwiki plugin.

Can you show the output of

pandoc -f docx+styles juste_liste.docx -t native

and

pandoc -f docx juste_liste.docx -t native

respectively? There must be a change in the AST that will explain why this is happening.
Generally pandoc will fall back to raw HTML when a list contains a feature that is too complex to represent using regular dokuwiki syntax.

Here they are :

pandoc -f docx+styles juste_liste.docx -t native

[ BulletList
    [ [ Div
          ( "" , [] , [ ( "custom-style" , "List Paragraph" ) ] )
          [ Para [ Str "Liste" , Space , Str "1" ] ]
      ]
    , [ Div
          ( "" , [] , [ ( "custom-style" , "List Paragraph" ) ] )
          [ Para [ Str "Liste" , Space , Str "2" ] ]
      ]
    , [ Div
          ( "" , [] , [ ( "custom-style" , "List Paragraph" ) ] )
          [ Para [ Str "Liste" , Space , Str "3" ] ]
      , BulletList

OK, it's the Div that is inserted for custom-styles that is blocking the regular list.
However, the div isn't being represented in HTML anyway, so we can probably improve this.
