            Bug ID: 28087
           Summary: Vertical text is the wrong way around by default
           Product: TextTracks CG
           Version: unspecified
          Hardware: PC
               URL: http://dev.w3.org/html5/webvtt/

Reported in https://code.google.com/p/chromium/issues/detail?id=411876

line:10% centers the text on a point 10% from the left edge for both
vertical-rl and -lr, but the interpretation of line:10 is different for
vertical-rl and vertical-lr.

Using line:0 does the right thing, but the (computed) default is -1.

Relevant steps from "Adjust the positions of boxes according to the appropriate
steps from the following list:"

> 8. Vertical Growing Left: Add one to line position then negate it.

> 10. Vertical Growing Left: Decrease position by the width of the bounding box of the boxes in boxes, then increase position by step.

Switching both of these steps to Vertical Growing Right ought to inverse the
behavior.

> 12. Vertical: Move all the boxes in boxes right by the distance given by position.

It looks odd that this is unconditional. May not be related, though.
