Failure to resolve name collision in local item

The following code is accepted by rustc, but is rejected as a hard error by RA, since RA believes Box to be std::Box. If I move Box outside of the function block, it both compiles and is accepted by RA.

struct X;

impl X {
    pub fn mk_box() -> impl std::fmt::Debug {

        #[derive(Debug)]
        struct Box {
            height : u64,
            width : u64,
        }

        impl Box {
            pub fn new(height : u64, width : u64) -> Box {
                Box { height, width }
            }
        }

        Box::new(1, 2)
    }
}

fn main() {
    let _x = X::mk_box();
    println!("x : {:#?}\n", _x);
}

Hovering on the error shows the docs for std::Box, with the message:

Expected 1 argument, found 2

This is a duplicate of #1559 I'd say.

Thanks, I guess I just didn't look hard enough.
