[webvtt] Wrong description for computing "x/y-position"

== Wrong description for computing "x/y-position" ==
https://w3c.github.io/webvtt/#processing-model

> If the WebVTT cue snap\-to\-lines flag is set, then run the 
appropriate steps from the following list:​

If I understand correctly, the y-position should be computed when the 
WebVTT cue's writing direction is horizontal, and x-position for the 
vertical writing direction.

Think about that, we set y-position be 0 in above step 6, and said 
it's "temporary positions used to calculate box dimensions below." 
However, we still set the x-position in following steps, so that the 
y-position still be zero and it seems like a serious error.
