Rustdoc produces strange output for pub use ::foo; items

[dbeckwith]

cargo doc produces some strange-looking documention for the following code:

// in lib.rs
pub mod foreign {
    pub use ::chrono;
    pub use ::mime;
    pub use ::url;
    pub use ::uuid;
}

The produced documentation for the foreign module in this crate looks like:

Re-exports

pub use {{root}}::chrono;
pub use {{root}}::mime;
pub use {{root}}::url;
pub use {{root}}::uuid;

I'm not sure why the {{root}} parts are there, I guess they're indicating the leading :: from the crate paths in my use statements but I feel like they should just render like the normal Rust syntax:

Re-exports

pub use ::chrono;
pub use ::mime;
pub use ::url;
pub use ::uuid;
