Ugly formatting of JS arithmetic operators with chained method calls

[rjkz808]

Prettier 2.0.5
Playground link

--parser babel

Input:

class App {
  doSomething() {
    window.addEventListener('click', () => {
      user.someValue = 1 + 1 + 1 + config.app.numbers
        .reverse()
        .findIndex((value) => user.someValue >= value);
    });
  }
}

Output:

class App {
  doSomething() {
    window.addEventListener("click", () => {
      user.someValue =
        1 +
        1 +
        1 +
        config.app.numbers
          .reverse()
          .findIndex((value) => user.someValue >= value);
    });
  }
}

Expected behavior:

I'd like Prettier to format this code the same way as my input was formatted initially. When the code has four levels of nesting (which is a common case when using ES6 classes for example), Prettier can format expression which has just a single '+' operator this way:

Doesn't it look ugly?
