arabic in chinese
Test passes if the order and rotation of Arabic characters is the same, and the letters are joined in the same way.

Assertion: [Exploratory test] Setting writing-mode to vertical-rl will cause Arabic text embedded in vertical Chinese to flow up the page, with letters rotated to the right, and wrap to the left, such that the Arabic lines are read right to left, and the letters join correctly.
This is an exploratory test because the CSS3 Text module that defines writing-mode is not yet a Recommendation.
