Methods from Deref impl aren't filtered by type parameters in Rustdoc

[sfackler]

use std::ops::Deref;

pub struct Ref<T>(T);

pub struct FooInner;

pub struct Foo(Ref<FooInner>);

impl Ref<FooInner> {
    pub fn foo(&self) {}
}

impl Deref for Foo {
    type Target = Ref<FooInner>;

    fn deref(&self) -> &Ref<FooInner> {
        &self.0
    }
}

pub struct Bar;

impl Ref<Bar> {
    pub fn bar(&self) {}
}

Note that bar is visible in the documentation even though it's only implemented for Ref<Bar>.
