Find all usages skips usages in derives

Consider the following minimal example:

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize)]
struct X {
    x: i32,
}

fn main() {
    println!("Hello, world!");
}

Use f12 on Deserialize to go to definition, then shift-alt-f12 to find all references. Note that the only reference in main.rs is in the use, not on the derive. This was initially found at https://github.com/rust-lang/rust-analyzer/pull/14723#issuecomment-1674760317. I believe the bug holds more generally with usages in proc-macros. This causes issues when running remove unused imports in a file which has serde derives in it.

rust-analyzer version: rust-analyzer version: 0.3.1631-standalone (83b3ba1b8 2023-08-19)

rustc version: rustc 1.73.0-nightly (0d95f9132 2023-07-26)

Reproduce the report in main.rs using the minimal serde example, then compare F12 definition results with Shift-Alt-F12 references for Deserialize. Done means usages inside the derive are included alongside the use statement, and removing unused imports no longer treats the serde import as unused.
