Macro errors in working code (rust-analyzer master, 90ccf4f5adf)

[osa1]

Tried with 5fe8cb1 (current master).

Cargo.toml:

[package]
name = "macro_test"
version = "0.1.0"
authors = []
edition = "2018"

[dependencies]
futures = { version = "0.3", default-features = false, features = ["std", "async-await"] }
tokio = { version = "0.3.6", features = ["time"] }

main.rs:

use futures::future::Fuse;
use futures::select;
use tokio::time::Sleep;

fn main() {}

async fn _test(mut x: Fuse<Sleep>, mut y: Fuse<Sleep>) {
    select! {
        () = x => {},
        () = y => {},
    }
}

Error:
