rustc version: rustc 1.87.0 (17067e9ac 2025-05-09) (stable)

editor or extension: Helix

relevant settings: cargo.features = 'all'

code snippet to reproduce:

let x = 0;
_ = x;
#[cfg(any())]
_ = x;

• trigger a rename on x
• only the declaration and first use are renamed

relevant: #16346

This is expected, and kinda not a bug. r-a cannot analyze cfg'ed out code.
