Yeah, I noticed (http://krijnhoetmer.nl/irc-logs/css/20110325#l-6)
when smontagu landed a patch in Gecko a few weeks ago (though I
think the patch ended up backed out, for now), but forgot to report
it.  Thanks for bringing this up and fixing it.

bidi-004a is intended to be a simplified version of bidi-004 that
doesn't test interaction with whitespace collapsing, since we had (I
think) no correct implementations of the interaction of bidi with
whitespace collapsing, and had to loosen the spec to enter PR.  For
(some) more details, see:
