Version: **15.0.0-rc.1**
Fiddle: https://jsfiddle.net/69z2wepo/33980/ (check console)

For an example providing `NaN` to a css property will result in "_NaN is an invalid value for the fontSize css style property_".
Now I'm aware that there is an error in my code but I have no idea which component I should check.
I would like to have something like this: "_NaN is an invalid value for the fontSize style property. Check the render method of Header_".
I'll be happy to try to solve this if this is something we want to do.

ReactDOM.render(<span><p /></span>, p);
      expect(console.error.calls.length).toBe(1);
      expect(console.error.argsForCall[0][0]).toBe(
        'Warning: validateDOMNesting(...): <p> cannot appear as a descendant ' +
        'of <p>. See p > ... > p.'
      );
    });
    it('warns nicely for table rows', () => {
      spyOn(console, 'error');
      var Row = React.createClass({
        render: function() {
          return <tr />;
        },
      });
      var Foo = React.createClass({
        render: function() {
          return <table><Row /> </table>;
        },
      });
      ReactTestUtils.renderIntoDocument(<Foo />);
      expect(console.error.calls.length).toBe(2);
      expect(console.error.argsForCall[0][0]).toBe(
        'Warning: validateDOMNesting(...): <tr> cannot appear as a child of ' +
        '<table>. See Foo > table > Row > tr. Add a <tbody> to your code to ' +
        'match the DOM tree generated by the browser.'
      );
      expect(console.error.argsForCall[1][0]).toBe(
        'Warning: validateDOMNesting(...): #text cannot appear as a child ' +
        'of <table>. See Foo > table > #text.'
      );
