rustdoc links to non-blanket impl for blanket impl in sidebar

[Nemo157]

I tried this code:

pub trait Something {}

pub trait AnAmazingTrait {}

impl<T: Something> AnAmazingTrait for T {}

pub struct AnotherStruct<T>(T);

impl<T: Something> Something for AnotherStruct<T> {}
impl AnAmazingTrait for AnotherStruct<()> {}

I expected to see this happen: Two links in the sidebar of AnotherStruct to AnAmazingTrait, one under "Trait Implementations" going to the specific impl, another under "Blanket Implementations" going to the blanket impl.

Instead, this happened: Two links in the sidebar, but both link to the specific impl.
