Description: Mongolian script is typically written in a left-to-right (vertical) text direction. Currently, vertical text direction options are only shown for "Asian" languages. These options should also be shown for Mongolian script, which in our language trichotomy is considered CTL. Steps to Reproduce: 1. Enable CTL support. 2. Type some Mongolian script, and set the paragraph language to Mongolian Mongolian (CTL). 3. Try to change the page text direction to Left-to-right (vertical). Actual Results: The text direction drop-down is present, but does not include vertical options. Expected Results: Mongolian script users should be able to choose left-to-right (vertical) text direction.
