### Bug description

Quarto 1.2.335 on Mac OS X 12.6.1 seems to render a list only, if there is an empty line before the list. So the following quarto file `test.qmd` will not render the list
```

title: "Introduction to markdown lists"
subtitle: ""

## Introduction to lists

This is an example of a list
- first item  
- second item
- third item
```
To make this example work as expected ( see [babelmark](https://babelmark.github.io/?text=a+list%0A-+item+1%0A-+item+2) ), one has to add an empty line before the list like
```
This is an example of a list

- first item  
- second item
- third item
```
One could argue this is just a documentation bug, because it is not mentioned in https://quarto.org/docs/authoring/markdown-basics.html#lists . 

However it leads to inconsistent behaviour when rendering iPython notebooks with quarto. The following notebook `test.ipynb` 
```
{
 "cells": [
  {
   "cell_type": "raw",
   "metadata": {},
   "source": [
    "---\n",
    "title: \"Introduction to markdown lists\"\n",
    "subtitle: \"\"\n",
    "author: Mark Down\n",
    "date: 2023-01-02\n",
    "---"
   ]
  },
  {
   "cell_type": "markdown",
   "metadata": {},
   "source": [
    "## Introduction to lists\n",
    "\n",
    "This is an example of a list\n",
    "- first item  \n",
    "- second item\n",
    "- thrid item"
   ]
  }
 ],
 "metadata": {
  "kernelspec": {
   "display_name": "Python 3",
   "language": "python",
   "name": "python3"
  },
  "language_info": {
   "name": "python",
   "version": "3.10.6"
  },
  "orig_nbformat": 4,
  "vscode": {
   "interpreter": {
    "hash": "b0fa6594d8f4cbf19f97940f81e996739fb7646882a419484c72d19e05852a7e"
   }
  }
 },
 "nbformat": 4,
 "nbformat_minor": 2
}
```
will render the list correctly when using 
```
jupyter nbconvert --execute --to html test.ipynb
```
However it will not render the list  when using 
```
quarto render test.ipynb --execute
```
This inconsistent behaviour is annoying for users, because it means one has to change the markdown dialect inside jupyter notebooks when one wants to use quarto for rendering. 

I understand quarto is using pandoc under the hood, so this behaviour probably cannot be changed easily. But maybe an option in the preamble could be given when rendering jupyter notebooks, to let quarto select the correct renderer for a given jupyter notebook. 

P.S.
