Current and expected behavior

Babel generates

    static get x() {
      return _C.#A;
    }
    static set x(v) {
      _C.#A = v;
    }

but it should generatr

    static get x() {
      return this.#A;
    }
    static set x(v) {
      this.#A = v;
    }

Or maybe it's a bug in the proposal: tc39/proposal-decorators#529 (comment)

Babel used to output this, the current behaviour was introduced in the 2023-05 version for the normative updates in Mar 2023.
