Docs produce invalid type when using bounds in associated type position

When using bounds in associated type position on a re-exported function or trait from another crate, the docs produces invalid type.

// In crate A
pub fn debug_iter() -> impl Iterator<Item: core::fmt::Debug> {
    core::iter::empty::<u8>()
}

// In crate B
pub use A::debug_iter;

// cargo doc -p A
pub fn debug_iter() -> impl Iterator<Item: Debug>

// cargo doc -p B
pub fn debug_iter() -> impl Iterator + Debug
