Thanks.  I think I see the problem: it's the auto-composition of
characters, in this case the Hebrew diacritics with the consonants.
Disable global-auto-composition-mode, and the problem goes away.  I
think shr.el's line-filling algorithm isn't ready for that, perhaps
because going back a character doesn't necessarily change point's
coordinates.

I will look into that, thanks for a clear test case.
