document leak for iframe directive

[IL55]

Hi,
I found strange thing, when I use iframe-based angular directive like this

   <iframe ng-src="https://github.com/%7B%7Burl%7D%7D"></iframe>

I found that number of documents increased, I controlled this parameter via chrome -> developer tools -> timeline. I fired manually gc a number of times but documents count stay unchanged.
I use latest version of chrome i.e. Version 32.0.1700.102 m and angular, i.e. Angular 1.2.10.

This example not mine, but I see the same behavior, if you press to the button you can see that number of DOM documents increased (and never decreased).

Does it mean that I forget something like this:

     scope.$on('$destroy', function(){
                $element.find('#myframe').off();
                $element.find('#myframe').remove();
                $element.off();
            });

Or it is chrome/angular bug ?

Thanks,
Igor

I took a quick peek and it looks like a chrome/v8 bug similar to the one we were chasing down at #4864

@IL55 you shouldn't need to do anything. it's web inspector + v8 bug.
