VTTCue.positionAlign now uses PositionAlignSetting instead of AlignSetting

Published: | Categories: Audio & Video


Previously, Firefox was incorrectly using an AlignSetting for the VTTCue.prototype.positionAlign property so that the value could be start, center, end, left or right. Firefox 49 follows the latest WebVTT spec to take and return a PositionAlignSetting which is line-left, center, line-right or auto.
