Markdown blockquotes with lists do not render as expected

[pawelrapacz]

I've set a markdown file as main page in doxygen and noticed that lists in blockquotes look wierd.
When creating a list in a blockquote the output seems to be incorrect. (without any text above the list in blockquote)

Example 1

Markdown code:

> - first element
> - secod element
> - third element
> - fourth element
> - fifth element

Expected output:

• first element
• secod element
• third element
• fourth element
• fifth element

Doxygen output:

Generated html:

<blockquote class="doxtable">
    <p>‍- first element</p>
    <ul>
        <li>secod element</li>
        <li>third element</li>
        <li>fourth element</li>
        <li>fifth element </li>
    </ul>
</blockquote>

Example 2

Markdown code:

> 1. first element
> 2. secod element
>    1. nested element
>       - nested element
>    2. nested element
> 3. third element
> 4. fourth element
> 5. fifth element

Expected output:

1. first element
2. secod element
   1. nested element
      • nested element
   2. nested element
3. third element
4. fourth element
5. fifth element

Doxygen output:

Generated html:

<blockquote class="doxtable">
    <p>‍1. first element</p>
    <ol type="1">
        <li>secod element
            <ol type="a">
                <li>nested element
                    <ul>
                        <li>nested element</li>
                    </ul>
                </li>
                <li>nested element</li>
            </ol>
        </li>
        <li>third element</li>
        <li>fourth element</li>
        <li>fifth element </li>
    </ol>
</blockquote>

Example 3 - here it looks ok

Markdown code:

> Text above the list
> - first element
> - secod element
> - third element
> - fourth element
> - fifth element

Expected output:

Text above the list

• first element
• secod element
• third element
• fourth element
• fifth element

Doxygen output:

Generated html:

<blockquote class="doxtable">
    <p>‍Text above the list</p>
    <ul>
        <li>first element</li>
        <li>secod element</li>
        <li>third element</li>
        <li>fourth element</li>
        <li>fifth element </li>
    </ul>

Version
1.13.0 (on Windows 10)

[doxygen]

@pawelrapacz Please verify if the referenced commit fixes the problem for you. Do not close the issue, this will be done automatically when the next official release becomes available.

This should also fix more complex cases like:

Text
> > - first element
> > - secod element
> - third element
> - fourth element
> - fifth element
1. sixth element
2. seventh element

@doxygen
Looks like first problem is solved, but second problem (regarding a as list item) is not solved, this looks like to be present in HTML and LaTeX

[doxygen]

@albert-github The label type to use for nested ordered lists is not really standardized in Markdown it seems. Doxygen's labels were added in 1.3.8, years before Markdown support was added. See for instance htmldocvisitor.cpp:

static const int NUM_HTML_LIST_TYPES = 4;
static const char types[][NUM_HTML_LIST_TYPES] = {"1", "a", "i", "A"};

Note that Github renders

1. One
   1. One-One
      1. One-One-One
          1. One-One-One-One
             1. One-One-One-One-One
                1. One-One-One-One-One-One

as

1. One
   1. One-One
      1. One-One-One
         1. One-One-One-One
            1. One-One-One-One-One
               1. One-One-One-One-One-One

while https://spec.commonmark.org/dingus/ just gives only 1 at each level.

So different behavior on different places, the main question will be: which "standard" to follow or give our own interpretation..
I have no real answer to it at the moment..
