Steps to reproduce

parse

-	-	text
	
	more text

which has the structure

{
    "type": "root",
    "children": [
        {
            "type": "list",
            "ordered": false,
            "children": [
                {
                    "type": "listItem",
                    "checked": null,
                    "children": [
                        {
                            "type": "list",
                            "ordered": false,
                            "children": [
                                {
                                    "type": "listItem",
                                    "checked": null,
                                    "children": [
                                        {
                                            "type": "paragraph",
                                            "children": [
                                                {
                                                    "type": "text"
                                                }
                                            ]
                                        }
                                    ]
                                }
                            ]
                        },
                        {
                            "type": "paragraph",
                            "children": [
                                {
                                    "type": "text"
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ]
}

Expected behavior

structure should remain

{
    "type": "root",
    "children": [
        {
            "type": "list",
            "ordered": false,
            "children": [
                {
                    "type": "listItem",
                    "checked": null,
                    "children": [
                        {
                            "type": "list",
                            "ordered": false,
                            "children": [
                                {
                                    "type": "listItem",
                                    "checked": null,
                                    "children": [
                                        {
                                            "type": "paragraph",
                                            "children": [
                                                {
                                                    "type": "text"
                                                }
                                            ]
                                        }
                                    ]
                                }
                            ]
                        },
                        {
                            "type": "paragraph",
                            "children": [
                                {
                                    "type": "text"
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ]
}

Actual behavior

content is stringified as

*   *   text
    more text

which has the structure

{
    "type": "root",
    "children": [
        {
            "type": "list",
            "ordered": false,
            "children": [
                {
                    "type": "listItem",
                    "checked": null,
                    "children": [
                        {
                            "type": "list",
                            "ordered": false,
                            "children": [
                                {
                                    "type": "listItem",
                                    "checked": null,
                                    "children": [
                                        {
                                            "type": "paragraph",
                                            "children": [
                                                {
                                                    "type": "text"
                                                }
                                            ]
                                        }
                                    ]
                                }
                            ]
                        }
                    ]

What settings are you using?

import {fromMarkdown as from} from 'mdast-util-from-markdown'
import {toMarkdown as to} from './index.js'

const doc = `
-	-	text

	more text`

console.log(to(from(doc)))

Yields:

*   *   text

    more text

Hi! Thanks for taking the time to contribute! This has been marked by a maintainer as needing more info. It’s not clear yet whether this is an issue. Here are a couple tips:

• Spend time framing the issue! The more time you put into it, the more we will
• Often, maintainers respond with why for several back and forths; rubber duck debugging might help avoid that
• Folks posting issues sometimes fall for xy problems: asking for a certain solution instead of raising the root problem

Thanks,
— bb

I tried it wrapped in remark, with the defaults

Hi! This was closed. Team: If this was fixed, please add phase/solved. Otherwise, please add one of the no/* labels.

[wooorm]

hmm, think I referenced the wrong issue

[wooorm]

Your reproduction does not match the example you use here. Your reproduction is not a paragraph in a list: https://spec.commonmark.org/dingus/?text=-%20%20-%20text%0A%20%20%0A%20%20more%20text.

One space is missing. Add an extra space before the paragraph to make it part of the list!
