Missing PlaceMention for scrutinee in #[loop_match]

[bjorn3]

I tried this code:

#![allow(incomplete_features)]
#![feature(loop_match)]

enum State {
    A,
}

fn main() {
    let mut state = State::A;
    #[loop_match]
    'a: loop {
        state = 'blk: {
            match state {
                State::A => {
                    #[const_continue]
                    break 'blk State::A;
                }
            }
        };
    }
}

I expected to see this happen: There is a PlaceMention for state.

Instead, this happened: There is no PlaceMention for state.
