           Summary: INVALID_STATE_ERR error upon calling .addCue() for an
                    alread-in-use cue
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified

        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Media Elements

The first test of the Opera-submitted test at http://w3c-test.org/html/tests/submission/Opera/media/interfaces/TextTrack/addCue.html fails because we try adding a cue to a TextTrack and that cue was already added to a previous track. The spec says that the cue must first be removed from the previous track before being added to the new track (http://www.whatwg.org/specs/web-apps/current-work/multipage/the-video-element.html#dom-texttrack-addcue). However, when we try to do that we get an INVALID_STATE_ERR error thrown, which is odd because the .addCue() method does not seem to throw exceptions.
