Renaming use alias renames the aliased symbol instead

[Veetaha]

I'd expect that renaming the alias would rename the alias itself, but not the underlying symbol (especially if the underlying symbol comes from std or some other crate):

Code to play with:

mod foo {
    pub(crate) fn bar() {}
}

use foo::bar as baz;

pub fn run() {
    baz();
}

I have some code like this in lib.rs:

mod folding {
    mod ascii {
        pub fn eq() {}
    }

    pub use ascii::eq as ascii_case_eq;
}

pub use folding::ascii_case_eq;

Renaming eq function in the ascii module to case_eq leaves the alias in the folding module untouched but renames the outermost pub use folding::ascii_case_eq to pub use folding::case_eq.
