This has got to be wrong too.  I don't think we need to fix these all in this
CL, but we should flag them with a FIXME comment that we can grep for and fix in
a followup CL.

                 WEBVTT_ADVANCE_TO(TagState);
             else
                 return emitAndResumeIn(source, WebVTTTokenizerState::TagState);
