Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Affected package

react-markdown@10.1.0

Steps to reproduce

import Markdown from 'react-markdown'

function App() {
  const markdown =`

1. **A1**
      * B1
      * B2
2. **A2**
      * B1
      * B2
`

const markdown2 = `
1. **A1**

      * B1
      * B2
2. **A2**
      * B1
      * B2
`

  return (
    <div className="App">
      <Markdown>{markdown}</Markdown>
      <br />
      <Markdown>{markdown2}</Markdown>
    </div>
  );
}

export default App;

Produces:

Actual behavior

In this example, markdown2's A2 is also contained in a <p> tag, which adds unintended margin

Actual:

Expected behavior

We expect this break to only add spacing to A1 (via the <p> tag), and not A2.

Welcome @7tint! 👋
We follow the commonmark spec. https://commonmark.org/
The behavior you describe is how commonmark works.
You can see it in the reference implmentation too

you can also see the same behavior on GitHub itself (also commonmark based)

1. A1

   • B1
   • B2

2. A2

   • B1
   • B2
