So the problem is the tspan. We don't handle the dy
properly with the Right to Left rendering. If you move
the tspan attributes to the text element it will work
properly.
<text id="boxtext_ar_1" y="30" x="80" text-anchor="middle"
font-size="8pt" font-style="normal" font-family="Traditional
Arabic">
<tspan x="80" dy="27">[some arabic text]</tspan>
</text>
