I agree with Roozbeh here. Since the hyphen marks a break in the middle
of the word, I think the most natural user expectation is that it should
appear after the last character in the word, where "after" and "last"
both refer to the reading direction of the word.

I have seen examples of this in published Hebrew books, and this is also
the way it's rendered in Chrome, Firefox and Opera (but in the case of
Firefox, since I wrote the code for it I can testify that it isn't this
way by design: as far as I remember I only took into account the
direction of the text run containing the soft hyphen and didn't even
think about the opposite-direction case).
