Formatting mdx, from v2.0.0 to v2.1.2 now a new line is introduced

[kuworking]

After upgrading Prettier from some version higher than 2.0.0, I see now that the formatting for a particular code has changed in mdx files

This code

# title

<Parenthesis>

CR: Carriage Return, \r
LF: Line Feed, \n

</Parenthesis>

was preserved by Prettier before (>2.0.0)

Now it gets an extra new line

# title

<Parenthesis>


CR: Carriage Return, \r
LF: Line Feed, \n

</Parenthesis>

My .prettierrc is this (prettier 2.1.2, eslint-config-prettier 6.11.0)

{
  "semi": false,
  "singleQuote": true,
  "trailingComma": "es5",
  "printWidth": 120,
  "arrowParens": "avoid"
}

How can I prevent this?

*Didn't inserted the playground because this code (changing <Parenthesis> for <div>) gives an error, but it should not)

EDIT:

I'm trying to downgrade Prettier, but somehow I can't see a consistent behavior

Going one by one to 2.0.3 has reverted the issue, then going upwards at 2.1.0 I had the correct behavior, and at 2.1.1 I had again the new extra line

But now I've downgraded directly to 2.0.0 and I see the same new line (but upgraded to 2.0.1 and I don't see it)

So I don't know what is happening (I'm using yarn)

Now I'm at 2.1.0 and I don't see the new line, so my bet is from 2.1.0 to 2.1.1 (https://github.com/prettier/prettier/blob/master/CHANGELOG.md#211)
