arabic in mongolian
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-lr will cause Arabic text embedded in vertical Mongolian to flow up the page, with letters rotated to the right, and wrap to the right, such that the Arabic lines are read left to right, and the letters join correctly.
This is an exploratory test because the CSS3 Text module that defines writing-mode is not yet a Recommendation.
