Bad formatting with closures

Formatting the following code produces awful results:

fn main() {
    {
        {
            {
                let result = this_is_a_quite_long_name(
                    another_long_one, 
                    &|from, to| -> LongResult<Words> {
                        () // this comment is to keep it from collapsing
                    }
                )?;
            }
        }
    }
}

it's formatted into this:

fn main() {
    {
        {
            {
                let result = this_is_a_quite_long_name(another_long_one, &|from,
                                                                           to|
                 -> LongResult<
                    Words,
                > {
                    () // this comment is to keep it from collapsing
                })?;
            }
        }
    }
}

playground: link

I can ignore it by using #[rustfmt::skip] but this behavior seems incorrect.

Start with the Rust playground reproduction linked in the issue and trace the formatter behavior for closures inside a long function call. Compare the current output with the reported input; done means this example is formatted without the closure signature being split and indented incorrectly.
