Can't reproduce on the latest RLS master with

trait Bar {
    fn some_fn(mut arg: bool, arg1: u32) {}
}

struct Foo;
struct Another;

impl Bar for Foo {
    fn some_fn(mut arg: bool, arg1: u32) {

    }
}

impl Bar for Another {
    fn some_fn(mut arg: bool, arg1: u32) {

    }
}

Go to Implementation on Bar, Foo, Another works as expected
