Please add a class specifying the resulting heading level of the title of the page to the div.wiki-content element

Now it is impossible to add multilevel numbering to the page headings in multipage PDF export.
It is because of enclosing page's heading elements (that may be demoted to h1,h2,h3,...h7 during page hierarchy building when exporting) into the div.wiki-content > div.pagetitle.
That's why calling smth. like h1

has no meaning because it will create a new instance of h1-title counter in the parent element div.wiki-content > div.pagetitle and will be popd after it is closed. And when a new div.wiki-content element (a new page) will be opened there will be a untouched counter value.

Please add a class to the div.wiki-content element that can classify the heading level (h1,h2,..h7) of the page title of the enclosed content (actually it will be enaught to copy the name of the type of the first child of the div.wiki-content > div.pagetitle element).

Something like this:

<div class="wiki-content h1">
<div class="pagetitle" id="Main topic">
<h1>Main topic</h1>
....
</div>
</div>
<div class="hidden rendered-page"></div>
<div class="wiki-content h2">
<div class="pagetitle" id="Subpage title">
<h2>Subpage title</h2>
