I have the same problem too. It drives me nuts. Even thinking of getting rid of WordPress. Nobody has an answer on that problem. And it is huge problem. At the moment I am translating a couple of hundreds of categories into 2 languages and each of them takes over 2 minutes waiting for pixel.wp.com.
How can that be corrected because on my widget.php page I have added a widget in an area but have put a wrong code, but in that area the widget is not visible anymore hence cannot correct or delete the code.
