  I don't know about that and leave it for Vafa to answer.

  That's understandable :-)

  So I realised.  But just in case, I think I'll change Polyglossia to
use luabidi instead of bidi if it's loaded with LuaTeX.  I had started
doing that in May 2013 but found out the output was very poor with
right-to-left as well as Indic-script languages, so I rolled back and
inserted the warning you saw ("[Hebrew] is not supported with LuaTeX,
etc.").  I will leave that warning, but will now load luabidi.  With all
its shortcomings, that may still prove useful for some users and will
mean they'll have one less hoop to jump through if they really want to
use LuaTeX for, say, Hebrew or Hindi.

  Fair enough, but my point was that you shouldn't try to make it
smaller than necessary.  I fully appreciate that the resulting example
may still be large, possibly too much so to let people navigate through
it easily, but if it stops exhibiting the concrete problem it's not
useful at all.
