Reference leak when doing Object.freeze

[Matthiee]

When I dispose the QuickJS engine I get a reference leak after doing a Object.freeze.

reference leak:
    ADDR	REF	TYPE	PROP
  986107159	1	_JSFunction	function () { ...
#0      new JSError
package:flutter_qjs/src/object.dart:93
#1      FlutterQjs.close
package:flutter_qjs/src/engine.dart:136
#2      main.<anonymous closure>

If I don't do the Object.freeze it all works fine.

To reproduce run this test code:

test('ref leak', () async {
    final qjs = FlutterQjs(timeout: 1000);

    int counter = 0;

    void click() => counter++;

    final myObj = {'click': click};

    final JSInvokable setToGlobal = await qjs.evaluate(
      '(name, obj) => { this[name] = obj; }',
    );

    setToGlobal.invoke(['myObj', myObj]);

    setToGlobal.free();

    // comment the following line and it will work.
    await qjs.evaluate('Object.freeze(myObj);');
    await qjs.evaluate('myObj.click();');

    expect(counter, 1);

    expect(
      () => qjs.close(),
      returnsNormally,
      reason:
          'There should be no reference leak when freezing an object in QuickJS',
    );
  });
