[webvtt] Issue: CR bug: support scrolling for vertically rendered text marked as i18n

r12a has just labeled an issue for https://github.com/w3c/webvtt as 
"i18n":

== CR bug: support scrolling for vertically rendered text ==
https://www.w3.org/Bugs/Public/show_bug.cgi?id=28268

The whole region concept has been defined for horizontal cues at this 
stage only, including scrolling.

We should generalize this for vertical cues and scrolling, but may be 
a v2 version.
