[2.7.0] GraphQL: empty lines inside comments unexpectedly removed

[jlowcs]

Prettier 2.7.0
Playground link

Input:

const typeDefs = gql`
  type User {
    """
    First line

    Second Line
    """
    value: String
  }
`

Output:

const typeDefs = gql`
  type User {
    """
    First line
    Second Line
    """
    value: String
  }
`

Expected behavior:

Unless I'm mistaken, the empty comment line should not be removed by prettier.

We're also seeing this on our project. Last version we were on was v2.6.2, so I think this might be related to #12519

Caused by #12608

You can try the fix with the ✨Try the playground for this PR✨-link in #13013 to verify the fix.

Sorry for the inconvenience.
