It looked like that, thanks for confirming.

To render this correctly, we should simply insert the appropriate
directional control characters. E.g., this page:
http://www.w3.org/International/questions/qa-bidi-unicode-controls
provides part of the story (look under "Correspondences"). It's not
the whole story, because text-align:right is not covered, but
supporting that is similarly simple.
Would it help if I provide an algorithmic description of what needs to
be done?
