Diagnostic doesn't mention cfg'ed out items if the unresolved path is simple (i.e., a single identifier)

[fmease]

Given the following code, I would've expected rustc to mention the cfg'ed out item Struct:

#[cfg(flag)]
struct Struct;

fn main() { let _ = Struct; } //~ ERROR cannot find type `Struct` in this scope

but it doesn't:

error[E0425]: cannot find value `Struct` in this scope
 --> file.rs:4:21
  |
4 | fn main() { let _ = Struct; }
  |                     ^^^^^^ not found in this scope

Only if you slightly tweak the input by replacing the simple path Struct with a complex one like self::Struct or crate::Struct, the note "found an item that was configured out" will show up:

#[cfg(flag)]
struct Struct;

fn main() { let _ = self::Struct; }

error[E0425]: cannot find value `Struct` in module `self`
 --> file.rs:4:27
  |
4 | fn main() { let _ = self::Struct; }
  |                           ^^^^^^ not found in `self`
  |
note: found an item that was configured out
 --> file.rs:2:8
  |
2 | struct Struct;
  |        ^^^^^^
note: the item is gated here
 --> file.rs:1:1
  |
1 | #[cfg(flag)]
  | ^^^^^^^^^^^^

CC #109005. I don't know if that's intentional or not.
