Failing example - error_chains can't cope with doc comments on links

lib.rs

//! Test crate
#![warn(missing_docs)]

#[macro_use]
extern crate error_chain;

/// Root errors
pub mod errors {
    error_chain!{
        links {
            /// Doc comment for links
            LinkedError(super::databases::Error, super::databases::ErrorKind);
        }
    }
}
use self::errors::*;

mod databases {
    /// Database errors
    mod errors {
        error_chain! {
            errors {
                /// Doc comment for internal error
                InternalError {
                    description("The database reported an internal error")
                    display("Database internal error")
                }
            }
        }
    }
    pub use self::errors::*;
}

/// Main entry point
pub fn run() -> Result<()> {
    Ok(())
