SWC Info output

No response

Expected behavior

No error when running the emitted code; decorator executes as expected.

tsc output for comparison:

class Foo {
    // ...
    static {
        __decorate([
            (Foo.#loggedMethod)
        ], Foo.prototype, "greet", null);
    }
}

Actual behavior

Emitted code references the private method outside the class

Uncaught SyntaxError: Private field '#loggedMethod' must be declared in an enclosing class

_ts_decorate([
    Foo.#loggedMethod
], Foo.prototype, "greet", null);
