Upgrade to 11.8 break sub-lists indented by 1 space

Summary

Upgrade to 11.8 break sub-lists indented by 1 space, which used to work in the past

Steps to reproduce

• Make a wiki page in Markdown with a numbered or bulleted list
• Indent a list item with a single space in order to make a sub-list
• The sub-list items are not indented, but rendered as part of the main list

Markdown:

List-test

• Hello there list item
• One space sub-list item

A regular paragraph of text

• Hello again list item
  • Two spaces sub-list item

Markdown file:

list_test.md

Example Project

Gitlab.com, https://gitlab.com/gunnarre/indentationproject/wikis/list-test

What is the current bug behavior?

The sub-list item(s) are shown un-indented

What is the expected correct behavior?

The sub-list item(s) should be indented to the level of the sub-list, not the parent list.
