RA cannot defer the type from a macro

rust-analyzer version: rust-analyzer version: 0.4.2369-standalone (588948f267 2025-04-06)

code snippet to reproduce:
cargo.toml

crabtime = "1.1.3"

fn main() {
    let x = {
        #[crabtime::eval_function()]
        fn boo2() {
            crabtime::output! {
                5u32
            }
        }
    };
}

RA reports x: () while with the expanded code from RA, it reports correctly u32
expanded:

let x = { 
#[doc = " # Compilation Stats"]
#[doc = " Start: 01:23:04 (771)"]
#[doc = " Duration: 0.50 s"]
#[doc = " Cached: false"]
#[doc = " Output Dir: /Users/indra/Code/git/flecs_rust/target/rust-analyzer/debug/build/crabtime/project_f940e44a8c006acd/pid_59609"]
#[doc = " Macro Options: MacroOptions {"]
#[doc = "     cache: true,"]
#[doc = "     content_base_name: false,"]
#[doc = " }"]
#[cfg(any())]
const _:() = ();
5u32
};

Reproduce the report using the dependency in cargo.toml and the crabtime macro snippet, then compare rust-analyzer's inferred type for x with the expanded code shown in the issue. The work is done when rust-analyzer reports x as u32 for this case rather than ().
