Incorrect preview of nested bulleted list

[thdoan]

Problem

Nested list indented by three spaces looks fine in the extension preview, but it wraps to one line in Bitbucket README.md.

How to reproduce

1. Create a dummy repo with this README.md file in Bitbucket:

1. Level one
   - Level two
   - Level two
2. Level one
3. Level one

2. Toggle the extension's Markdown: Open Preview to the Side.
3. Observe that the preview looks fine in VS Code.
4. Commit the changes and push to the repo.
5. Go to the repo index in Bitbucket.

ISSUE: The "Level two" bullets are on the same line as the first "Level one" bullet. It seems Bitbucket requires four spaces to nest lists. According to https://commonmark.org/help/tutorial/10-nestedLists.html you can have as little as two spaces to indicate a nested list, so can we conclude that Bitbucket's MD implementation is non-standard? If this is a case, feel free to close this ticket.

Looks just fine in the GitHub comment.

@yzhang-gh my bad, it was in Bitbucket, not GitHub. I have updated the issue details.

Bitbucket uses Python-Markdown not CommonMark. Python-Markdown requires "4 spaces" indentation:

• https://support.atlassian.com/bitbucket-cloud/docs/readme-content/
• https://bitbucket.org/tutorials/markdowndemo/src/master/#markdown-header-lists
• https://python-markdown.github.io/#differences

Please set the following in your Settings.

{
    "[markdown]": {
        "editor.detectIndentation": false,
        "editor.insertSpaces": true,
        "editor.tabSize": 4
    },
    "markdown.extension.list.indentationSize": "inherit"
}

This should be added as a setting inside the settings UI rather than a manual edit to the settings json file to make it easier on users to find.

[Lemmingh]

Aren't they present in the Settings (UI)?

Or, are you talking about

• Settings UI - Not Showing Language Specific fields microsoft/vscode#58995
• Exploration: Language-specific default overridden values and language-specific settings in the Settings editor microsoft/vscode#131707

The settings weren't showing until I manually added them to the settings.json. Then they showed up. Strange glitch maybe.
