Hebrew is a hard language
The Google folks are trying to eat their own dog food. But as it turns out, eating from right to left isn't as easy as eating left to right.
You see, the fact that Hebrew is written from right to left has been consuming significant computing resources since,well, the dawn of time I guess.
The issue has been mostly solved back in the 90's when Microsoft forced the "logical display order" standard (a.k.a implicit directionality, RFC 1556 and other names) on the industry.

Oh well. I am confident that Hebrew (and Arabic) will display perfectly soon after the introduction of peace to the middle east. Don't hold your breath on either one of them though :) .
