`use_self` with different lifetimes

[EdJoPaTo]

Summary

use_self seems to trigger even when the lifetimes are different here. Using --fix doesn't work as the resulting code doesn't compile. (Which is good that --fix doesn't try to fix anything then)

Noticed here: https://github.com/bevyengine/bevy/blob/423285cf1cbd86d85db066dbfe26de4fd68333d9/crates/bevy_ecs/src/system/system_param.rs#L537

Lint Name

use_self

Reproducer

#![warn(clippy::use_self)]
trait Foo {
    type Item<'foo>;
}
struct Bar<'b> {
    content: &'b str,
}
impl<'b> Foo for Option<Bar<'b>> {
    type Item<'foo> = Option<Bar<'foo>>;
}

I saw this happen:

warning: unnecessary structure name repetition
  --> src/main.rs:16:23
   |
16 |     type Item<'foo> = Option<Bar<'foo>>;
   |                       ^^^^^^^^^^^^^^^^^ help: use the applicable keyword: `Self`
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#use_self

I expected to see this happen: The lint should not trigger here. These are different lifetimes.
