Unable to `expect` the `missing_panics_doc` and `missing_errors_doc` lints on main function

Summary

My code base denies clippy::missing_panics_doc, clippy::missing_errors_doc and clippy::allow_attributes globally. However I also have a pub main function that doesn't need documentation.

If I use expect to allow the first two on main, clippy complains that the lint is unfulfilled - even though it has stopped complaining about the missing docs.

Everything works fine on functions that aren't main.

Reproducer

I tried this code:

#![deny(clippy::missing_panics_doc)]
#![deny(clippy::missing_errors_doc)]
#![deny(clippy::allow_attributes)]

use std::env::var;

#[expect(clippy::missing_panics_doc, reason = "main doesn't need docs")]
#[expect(clippy::missing_errors_doc, reason = "main doesn't need docs")]
pub fn main() -> Result<(), &'static str> {
    let val = var("Hello").unwrap();
    match val.as_str() {
        "hello" => Ok(()),
        _ => Err("Oh no"),
    }
}

I expected to see this happen:

No complaints from clippy

Instead, this happened:

Clippy complains about unfulfilled lints
