Description

trait Foo {
    type Item;
    type IntoItem;
}
impl<T: Foo> Foo for T {
    type Item = T::Item;
    type IntoItem = T::$0;
}

Current completion list

>>> Item(as Foo) type Item         S [LS]
    IntoItem(as Foo) type IntoItem S [LS]

Expect completion list

    Item(as Foo) type Item         S [LS]
>>> IntoItem(as Foo) type IntoItem S [LS]

This should be able to use exact_name_match

Research direction

No file or test is named. Start at the associated-type completion logic and inspect how exact_name_match is applied; reproduce the Foo example and confirm that IntoItem is selected at the IntoItem cursor while Item remains available above it.
