incorrect/useless lint warning [warn(dropping_references)]

when compiling something like

let x = [0; 64];
let _ = drop(&x);

I see

warning: calls to `std::mem::drop` with a reference instead of an owned value does nothing
 --> src/main.rs:3:9
  |
3 | let _ = drop(&x);
  |         ^^^^^--^
  |              |
  |              argument has type `&[i32; 64]`
  |
  = note: use `let _ = ...` to ignore the expression or result
  = note: `#[warn(dropping_references)]` on by default

warning: `playground` (bin "playground") generated 1 warning

which gives me the note: use let _ = ... to ignore the expression or result. (the reason for the let _ = ... in the first place is because i listened to the suggestion)

$ rustc --version
rustc 1.95.0 (59807616e 2026-04-14)

this also happens on nightly

$ cargo +nightly  --version

Start by reproducing the issue with the Rust snippet in the report and inspect the compiler's dropping_references lint diagnostics. Trace how the warning and its let _ = ... note are selected; done means the diagnostic no longer gives guidance that conflicts with the code that triggered it.
