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.

var ReactTestUtils = require('ReactTestUtils');
      spyOn(console, 'error');
      ReactTestUtils.renderIntoDocument(<div onScroll={function() {}} />);
      expect(console.error.calls.length).toBe(1);
      expect(console.error.argsForCall[0][0]).toBe(
        'Warning: This browser doesn\'t support the `onScroll` event'
      );
    });
    it('should not warn when server-side rendering `onScroll`', function() {
      spyOn(console, 'error');
      ReactDOMServer.renderToString(<div onScroll={() => {}}/>);
      expect(console.error).not.toHaveBeenCalled();
    });
  });
  describe('tag sanitization', function() {
    it('should throw when an invalid tag name is used', () => {
      var ReactTestUtils = require('ReactTestUtils');
      var hackzor = React.createElement('script tag');
      expect(
        () => ReactTestUtils.renderIntoDocument(hackzor)
      ).toThrow(
        'Invalid tag: script tag'
      );
    });
    it('should throw when an attack vector is used', () => {
      var ReactTestUtils = require('ReactTestUtils');
      var hackzor = React.createElement('div><img /><div');
      expect(
        () => ReactTestUtils.renderIntoDocument(hackzor)
      ).toThrow(
