Incorrect type mismatch label pointing at return type

[estebank]

The following code:

fn main() { //~ NOTE expected `()` because of default return type
  let s = "abc";
  let u: &str = if true { s[..2] } else { s };
}

has an incorrect label:

error[E0308]: mismatched types
 --> src/main.rs:3:27
  |
1 | fn main() { //~ NOTE expected `()` because of default return type
  |           - expected `()` because of default return type
2 |   let s = "abc";
3 |   let u: &str = if true { s[..2] } else { s };
  |                           ^^^^^^ expected &str, found str
  |
  = note: expected type `&str`
             found type `str`
