They prescribe a heuristic.  :-)

Well, Firefox displays the web page correctly without Firefox users
having to do anything in particular, so presumably eww should be able to
do the same, I would have thought?

That is, eww should leave `bidi-paragraph-direction' to nil (which makes
the Al Jazeera web page display correctly), and then it...  shouldn't be
so eager to switch the direction of paragraphs to rtl just because a
section starts with some rtl text.  Or something.
