Incorrect elided lifetime shown

rust-analyzer version: 0.3.2104-standalone (08c7bbc2d 2024-09-06)

rustc version: rustc 1.81.0 (eeb90cda1 2024-09-04)

editor or extension: VsCode, with rust-analyzer extension version v0.3.2104

relevant settings:

{
    "rust-analyzer.inlayHints.genericParameterHints.lifetime.enable": true,
    "rust-analyzer.inlayHints.lifetimeElisionHints.enable": "always",
}

code snippet to reproduce:

pub struct FooRef<'a>(pub &'a i32);

pub struct Foo(i32);

impl Foo {
    pub fn foo_as_ref(&self) -> FooRef<'_> {
        FooRef(&self.0)
    }
}

The elided lifetime for self and for FooRef should be shown as the same lifetime in the inlay hint. However, they're shown as different lifetimes.

Discovered by tionway on the rust community discord.

Start by reproducing the provided Rust snippet with lifetime elision hints enabled using the listed rust-analyzer settings. Compare the inlay hints for the elided lifetime on &self and FooRef<'_>; done means both display the same lifetime without changing unrelated hints.
