Cannot format too long str in nested match

[A4-Tacks]

fn main() {
    match () {
        () => match () {
            () => {
    postfix_snippet(
        "",
    foo("too ling string xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"),
)
    .foo();
            }
        },
    }
}

Run rustfmt output:

fn main() {
    match () {
        () => match () {
            () => {
                postfix_snippet(
        "",
    foo("too ling string xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"),
)
    .foo();
            }
        },
    }
}

The trailing .foo() makes this a chain so this is a duplicate of #3863.
