Multi-line Descriptions Cannot Contain Nested Lists

[PvtPuddles]

Describe the bug
According to the GraphQL spec, the description field can be multi-line and contain markdown-formatted text. I was disappointed to find out that when I run the introspection query, the leading whitespace gets removed and my nested lists get flattened.

To Reproduce

I have the following argument defined using the Sangria scala package:

object Args {
  val MyArg: Argument[Int] = Argument(
    "myArg",
    IntType,
    description = """My argument description
        |
        |- List level one
        |  - List level two
        |""".stripMargin
  )
}

I have verified that when running schema introspection manually, the string is correctly formatted by the server:

"description": "My argument description\n\n- List level one\n  - List level two\n"

However, when I run schema introspection with the graphQL plugin, I get the following:

 someEndpoint(
        """

        My argument description

        - List level one
        - List level two
        """
        myArg: Int!
): ???

Expected behavior
When I mouse over my argument, I expect to see a nested list.

Screenshots

This is how the description currently renders on hover:
