Nice catch. The approach looks nice. A few nits.

This function should be renamed to represent the returned scope is not generator's scope.
And please note that this function skips arrow function and generator, but it does not skip generator function.

Could you add tests like

method() {
    function *gen() {
         let arr = () => super.getValue();
         arr();
    }
}

This should be SyntaxError.
