Tuple struct with #derive shows field types as references in tooltip

[doxxx]

Given the following example:

#[derive(Debug)]
struct Bar {
    i: usize,
}

#[derive(Debug)]
struct Foo(Bar);

The hover tooltip for Bar in the Foo definition shows &module_name::Bar. If I remove the #derive lines, it shows Bar { i } as expected.

Additionally, when the #derive lines are present, Go To Definition does not work for Bar in the Foo definition. Remove the #derive lines and it works. Similarly for Find All References.
