Setting the direction attribute to "rtl" and unicode-bidi to "embed" on a text with arabic characters doesn't yield to the same result as other browsers (See comparison.jpg. Flash rendering seen at the center of the snaphot). In addition,
regardless of the combination used on direction attribute (either "ltr" or "rtl") and unicode-bidi attribute (either "embed" or "bidi-override"), the same rendering is produced.

Reproducible: Always

Steps to Reproduce:
1. Open the attached SVG document.
2. Compare to the reference image. The text is not rendered as expected. The expected result is the one shown by Batik squiggle (top right), Chrome (top left), Safari (bottom left) or Flash (center).
Actual Results:  
The glyphs are rendered left to right instead of right to left.

Expected Results:  
The glyphs are rendered right to left instead of left to right.

Attachment: Reference image

Reference rendering with other rendering engines: Chrome, Safari, Apache Batik, Flash.

The Flash rendering is a test rendering the same Arabic text using the Flash APIs, since Flash does not render SVG. Was created for reference purposes.
