If it is only about alignment, maybe you just need a custom stylesheet.
Maybe we can design a "rtl.css" stylesheet for use with RTL languages?
(Unfortunately, I don't understand any language that uses an RTL script.)

Did you set --language=arabic (or farsi, hebrew,...)?

You can also set the language for individual elements with the "class"
argument or "class" directive. A class value of "language-mylang" is
written as `lang=mylang` in HTML.

Looking at docutils/docs/ref/doctree.html, I realize that "dir" is not
standard attribute in Docutils. It seems to be an addition by the
"hibidy"-enhanced custom writer.

This shows that the problem is in the 3rt-party module "hibidy.py".
Maybe making line 97 failproof changing it to something like

     if not getattr(node, "dir"):

helps. (But I don't know which default to use and whether
there are other follow-up errors.)
