How to include auto-numbered lists in github_document?

问题

The below code works for auto-numbering lists in plain html:

---
title: "Assignment 1"
output: 
  html_document:
    number_sections: true
---

1. First

2. second

but how can I use auto-numbering to output a github_document?

UPDATE: this works for me after updating to pandoc 2.2.3.2 and RMarkdown 1.10 not sure if there are other ways

---
title: "Assignment 1"
output: github_document
---

#. First

#. second
