mdx v2: Should preserve newlines inside jsx

[ferdinandant]

Prettier 2.4.1
Playground link

--parser mdx

Input:

export function Message(props) {
  return props.children
}

<Message>
  aaa
  
  aaa
  
  aaa
</Message>

Output:

export function Message(props) {
  return props.children;
}

<Message>aaa aaa aaa</Message>

Expected behavior:
Newlines inside <Message> should be preserved because mdx (as of version 2) now treats them as separate paragraph
blocks. Try it here: https://mdxjs.com/playground/

export function Message(props) {
  return props.children
}

<Message>
  aaa
  
  aaa
  
  aaa
</Message>

I created #12209 to track MDX 2 support. I am going to close this issue in favour of a more generic one. Hope it’s fine 🤞
