[webvtt] AlignSetting values don't match what has been implemented in UAs

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

== AlignSetting values don't match what has been implemented in UAs ==
See 
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/core/html/track/vtt/VTTCue.idl?q=VTTCue.idl&sq=package:chromium&l=36
and 
http://mxr.mozilla.org/mozilla-central/source/dom/webidl/VTTCue.webidl#12
and 
http://trac.webkit.org/browser/trunk/Source/WebCore/html/track/VTTCue.cpp#L428

For some reason the spec has "center" but implementations "middle". It
 is unclear whether it is safe to change implementations and are 
others than Gecko considering the change.
