I tried documenting this code with cargo doc:

pub struct Struct;

pub trait Trait<T> {}

impl<S> Trait<Struct> for S {}

I expected to see this happen: The impl<S> Trait<Struct> for S {} blanket impl appears only once in the docs for Struct

Instead, this happened: The blanket impl appears 23 times.

Picture of the blanket impls in the docs for `Struct`
