Original indentation gets lost when printing non-file node

[Andarist]

I've attempted to only print a subset of the original file because I only want to replace that part through VS Code's WorkspaceEdits (I'm developing a VS Code extension). Replacing the whole file puts more pressure on the VS Code as it has to recompute syntax highlighting, code lenses, and more. And I know which part of the file I'd like to touch - so it's best to focus on that part.

However, I've discovered that in such a situation Recast dedents my result and removes the original indentation of this node.

Repro case

https://codesandbox.io/s/affectionate-curie-dvwykb?file=/src/index.js

import * as recast from "recast";
import * as babelParser from "recast/parsers/babel";

const ast = recast.parse(
  `
createMachine(
  {
    initial: 'foo'
  },
  {
    actions: {}
  }
)
`,
  {
    parser: babelParser
  }
);

const config = ast.program.body[0].expression.arguments[0];

config.properties[0].value = recast.types.builders.stringLiteral("REPLACED");

console.log(recast.print(config).code);

Actual

{
  initial: "REPLACED"
} 

Expected

  {
    initial: "REPLACED"
  }
