rustc version: rustc 1.79.0-nightly (ef8b9dcf2 2024-04-24)

editor or extension: VScode v0.3.1932

code snippet to reproduce:

mod inner {
    pub struct X();
    pub struct Y();
}

mod z {
    use super::inner::{self, X}$0;

    fn f() {
        let y = inner::Y();
    }
}

becomes

mod inner {
    pub struct X();
    pub struct Y();
}

mod z {
    use super::inner:self;

    fn f() {
        let y = inner::Y();
    }
}

which is invalid. It should be use super::inner instead.
