Make Static Site Editor list styling consistent with the Handbook Markdown Guidelines

Problem

Editing a page using the Static Site Editor that contains a mixed-style list results in formatting that is not consistent with the Handbook Markdown Guidelines.

Details

A simple example is

1. This is a list item
  * This is a sub-item using a bullet
1. This is the second list item
  * Another sub-item
1. This should be the third item.

Rendered in the Handbook, it looks like this:

1. This is a list item
   • This is a sub-item using a bullet
2. This is the second list item
   • Another sub-item
3. This should be the third item.

Rendered in this description block using GFM, however, it looks like:

1. This is a list item

• This is a sub-item using a bullet

2. This is the second list item

• Another sub-item

3. This should be the third item.

This is due to there only being 2 spaces preceding the sub-item asterisk.

Solution

Configure the Static Site Editor to format lists adhering to the Handbook-flavored markdown rules:

• List bullet char: -
• list indent space: 3 spaces
• increment ordered lists: false
