Auto import unresolved module and constant value with similarly name

rust-analyzer version: rust-analyzer 1.88.0-nightly (a15cce2 2025-04-17)

rustc version: rustc 1.88.0-nightly (a15cce269 2025-04-17)

editor or extension: VIM9.1 coc-rust-analyzer

code snippet to reproduce:

mod foo {
    pub mod bar {
        pub fn baz() {}
    }
    pub fn bar() {}
}
use foo::bar;

fn main() {
    let _ = bar();
    baz
}

On line 11 complete baz:

mod foo {
    pub mod bar {
        pub fn baz() {}
    }
    pub fn bar() {}
}
use foo::bar::{self, baz};

fn main() {
    let _ = bar();
    baz();
}

rustc: error[E0423]: expected function, found module `bar`

Expect:

mod foo {
    pub mod bar {
        pub fn baz() {}
    }
    pub fn bar() {}
}
use foo::{bar, bar::baz};

fn main() {
    let _ = bar();
    baz();
}

Clean reproduction of #10660

Start with the minimal Rust reproduction and the completion request for baz in the VIM9.1 coc-rust-analyzer example. Trace rust-analyzer's auto-import completion and name-resolution handling for a module and function sharing the name bar; done means the suggested import matches the expected use foo::{bar, bar::baz}; and compiles without E0423.
