[webvtt] [IR] VTTCue region test failing (#463)

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

== [IR] VTTCue region test failing ==
[This test](https://github.com/web-platform-tests/wpt/blob/master/webvtt/api/VTTCue/region.html) is failing across the board, currently.
Firefox is failing because it is throwing an error when `cue.region` is set to a value other than VTTRegion or null. An error is not supposed to be thrown.
Safari is failing due to its non-standard regions implementation. Chrome and Edge do not support regions.
