Malformed suggestion for E0061 when in macro context and method is a macro token

[nagisa]

Code

macro_rules! delegate {
    ($method:ident) => {
        <Self>::$method(8)
    }
}

struct Bar;

impl Bar {
    fn foo(a: u8, b: u8) {
    
    }
    fn bar() {
        delegate!(foo);
    }
}

Current output

error[E0061]: this function takes 2 arguments but 1 argument was supplied
  --> src/main.rs:3:9
   |
3  |         <Self>::$method(8)
   |         ^^^^^^^^^^^^^^^--- argument #2 of type `u8` is missing
...
14 |         delegate!(foo);
   |         -------------- in this macro invocation

note: associated function defined here
  --> src/main.rs:10:8

10 |     fn foo(a: u8, b: u8) {
   |        ^^^        -----
   = note: this error originates in the macro `delegate` (in Nightly builds, run with -Z macro-backtrace for more info)
help: provide the argument
   |
3  -         <Self>::$method(8)
3  +         <Self>::<Self>::$method(8, /* u8 */)
   |

Desired output

Should not add the extra ::<Self> in the suggestion.

Rationale and extra context

<Self>::<Self> is not valid Rust :)

Other cases

Rust Version

1.88.0-nightly (2025-04-29 74509131e85a97353c67)
