            Bug ID: 25948
           Summary: [WebVTT] The parser should not set the region to null
                    when e.g. size != 100
           Product: TextTracks CG
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebVTT
          Assignee: dave.null@w3.org
          Reporter: philipj@opera.com

"If cue's text track cue line position is not text track cue automatic line
position or cue's text track cue size is not 100 or cue's text track cue
writing direction is not horizontal, let cue's text track cue region be null."

"This makes sure that no matter in which order the cue settings are provided,
if if the cue has a text track cue line position or a text track cue size
setting or is text track cue vertical growing left or growing right writing
direction, the text track cue region will be ignored."

This should be part of the rendering algorithm, since scripts can change the
properties later to violate the invariant that this tries to preserve. To the
extent possible, providing the settings to the parser or with a script should
do the same thing.
