rust_2021_incompatible_closure_captures lint produces bad formatting

[m-ou-se]

#![warn(rust_2021_incompatible_closure_captures)]

fn main() {
    let a = ("hey".to_string(), "123".to_string());
    let _ = || {
        dbg!(a.0);
    };
}

suggests:

    let _ = || { let _ = &a; 
        dbg!(a.0);
    };

It adds let _ = &a; on the same line as the {. There's also an extra space after the ; there.

Instead, it'd be nice if it produced:

    let _ = || {
        let _ = &a;
        dbg!(a.0);
    };

Working on a fix.
