It is impossible. I mentioned that before, you can look for the 
explanation in the logs of this list.

In short, the geometry of the text cannot be expressed by the DOM. 
Imagine a huge pile of text with a floating element inside (image in 
text for example).

The DOM gives you a single element for a text. This element can be 
splitted inside the engine for the layout.
