[webvtt] Replace `max dimension` with `full dimension` in 7.2.10.9 (#450)

alastor0325 has just created a new issue for https://github.com/w3c/webvtt:

== Replace `max dimension` with `full dimension` in 7.2.10.9 ==
In 7.2. [Processing cue settings](https://www.w3.org/TR/webvtt1/#processing-cue-settings), step 10.9, 

> 9. If line is less than zero then increase position by max dimension, and negate step.

Here we should use `full dimension` that is defined in step 10.1, not `max dimension`.
