Markdown headings are not parsed inside WRAP containers

[Phildrim]

Dokuwiki's new Markdown support does not appear to parse Markdown headings inside WRAP containers.
Lists and quotes work correctly using the md+dw syntax flavor.

Steps to reproduce
Using the md+dw syntax flavor:

<WRAP>
# heading
- item
> quote
</WRAP>

Actual behavior

• # heading is rendered als normal text
• The list and quote are parsed correctly

Possible cause

The problem seem to be related to /lib/plugins/wrap/syntax/div.php
I tested adding 'baseonly' to function getAllowedTypes() { return array('container', 'formatting', 'substition', 'protected', 'disabled', 'paragraphs'); }
That fixed my heading problem but created problems with list via

<WRAP>
{{topic>test}}
</WRAP>

The problem seems to be that WRAP handles headings in doku-wiki syntax seperately because it isnt't only a formatting issue:

case DOKU_LEXER_MATCHED:
                // we have a == header ==, use the core header() renderer
                // (copied from core header() in inc/parser/handler.php)
                $title = trim($match);
                $level = 7 - strspn($title,'=');
                if($level < 1) $level = 1;
                $title = trim($title,'=');
                $title = trim($title);

It may therefore require similar handling for headings produced by the Markdown parser.
