Failure to parse macro converting a `stmt` into a `block`

rust-analyzer version: rust-analyzer version: 5e8515870 2022-03-14 stable

rustc version: rustc 1.59.0 (9d1b2106e 2022-02-23)

relevant settings: don't think I have anything custom

More or less minimal example:

fn main() {
    macro_rules! parse {
        ($action:block) => ($action);

        ($action:stmt) => (
            parse!({ $action })
        );
    }

    parse!(let _ = 1);
}

rust-analyzer errors with "expected Block", meanwhile rustc expands this fine into:

fn main() {
    {
        let _ = 1;
    };
}

Adding ; manually, i.e. parse!({ $action; }), makes r-a parse/expand it correctly but produces an "unnecessary trailing semicolon" warning.

Start with the minimal macro_rules! parse! reproducer in the issue and compare rust-analyzer's result with rustc's shown expansion. Done means the stmt-to-block case parses and expands without the erroneous "expected Block" error, while the workaround's unnecessary trailing-semicolon warning is not required.
