nested ordered lists in rmarkdown

Question

I have observed a strange in nested ordered lists while using rmarkdown.

From here, the order of the numbers is ignored in the main list of items. Both of the below set produce the same output.

#set 1:
1.  one
2.  two
3.  three

#set 2:
5.  one
7.  two
1.  three

However, it is not the case in nested list of items.

#set 3:
1.  one
    5.  one
    7.  two
    1.  three
2.  two
3.  three

How to achieve automatic ordering of nested list of items in rmarkdown?

Answer 1

Cf. the next section of the documentation (my emphasis):

Pandoc also pays attention to the type of list marker used, and to the starting number, and both of these are preserved where possible in the output format.

To get the output you want (all new list should begin at 1.), disable the startnum extension (source):

---
output: 
  html_document:
     md_extensions: -startnum
---
