Can we locate the line number when react makes a warning like this "Unknown DOM property class. Did you mean className?"

There is no hint about which code made this warning.

spyOn(console, 'error');
      for (var i = 0; i < 3; i++) {
        var container = document.createElement('div');
        var element = React.createElement(
          'x-foo-component',
          {'blah" onclick="beevil" noise="hi': 'selected'},
          null
        );

        'Warning: Invalid attribute name: `blah" onclick="beevil" noise="hi`'
      );
    });
    it('should reject attribute key injection attack on update', function() {
      spyOn(console, 'error');
      for (var i = 0; i < 3; i++) {
        var container = document.createElement('div');
        var beforeUpdate = React.createElement('x-foo-component', {}, null);
        ReactDOM.render(beforeUpdate, container);
        var afterUpdate = React.createElement(
          'x-foo-component',
          {'blah" onclick="beevil" noise="hi': 'selected'},
          null
        );
        ReactDOM.render(afterUpdate, container);
