Multi-level lists do not render correctly

[hidegh]

Describe the bug
Multi-level lists do not render correctly

Issue 1: it uses simple numbering instead of "multi-level list" (which, on 1 level, is de facto the same).

If I change it to multi level, other issues emerge:

Issue 2: here the content of the list-item is rendered as an item that is nested another 2 levels below (See docx vs html)

Issue 3: similar to the previous one, but when I started to use the 2nd level nesting, the first 2 levels were correct, but the real content is not another +1 level below (see docx vs html = output vs expected):

Expected behavior
Multi-level listsrenders correctly - very close display to the HTML
