Visual ident style of `if` in closure is wrong

This

fn test() {
    let aaaaaaaaaaaaaaaa = ffffffffffffffffffffffff
        .iter()
        .filter_map(|_| {
            if bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
                == ccccccccccccccccccccccc
                    .dddddddddddddddddddddddd()
                    .eeeeeeeeeeeeeeeeeeeeee()
            {
                ();
            }
        })
        .collect();
}

is turned into this

fn test() {
    let aaaaaaaaaaaaaaaa = ffffffffffffffffffffffff.iter()
                                                   .filter_map(|_| {
                                                       if bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
                == ccccccccccccccccccccccc
                    .dddddddddddddddddddddddd()
                    .eeeeeeeeeeeeeeeeeeeeee()
            {
                ();
            }
                                                   })
                                                   .collect();
}

Start by reproducing the Rust input and output shown in the issue with rustfmt. Trace formatting for an if expression inside a closure, then verify that the chained calls and the closure body are indented consistently without changing the intended formatting.
