Appendix E defines "tree order" to mean

   # Preorder depth-first traversal of the rendering tree, in logical
   # (not visual) order for bidirectional content, after taking into
   # account properties that move boxes around such as the 'run-in'
   # value of 'display'.

I was under the distinct impression that there is no guarantee that the 
rendering structure is a tree.

Also, what does "preorder" mean here?
