`if_let_guard` + `let_chains`: used binding is possibly-uninitialized

[y21]

I tried this code:

#![feature(if_let_guard, let_chains)]

fn main() {
    let opt = Some(1);
    match 1 {
        1 | 2
            if let Some(x) = opt
                && true =>
        {
            x;
        }
        _ => {}
    }
}

I expected to see this happen: the code compiles.

Instead, this happened: it doesn't compile.

error[E0381]: used binding `x` is possibly-uninitialized

If I remove the && true, it does compile.
