This looks like a hack.
Given that only one axis could be actually resized and we don't need dimensions
of the other, we should not use Size here as data for the event.

We have plans for two-dimensional resize aswell, which will use the same event.

         if (event.target.isVertical())
             requested.height = newSize;
         else
