// HAVE_METADATA and dispatching 'loadedmetadata' may occur, since the
// initialization segment is uncorrupted and forms the initial part of
// the appended bytes. The segment parser loop continues and
// eventually should observe decode error. Other implementations may
// delay such transition until some larger portion of the append's
// parsing is completed or until the media element is configured to
// handle the playback of media with the associated metadata (which may
// not occur in this case before the MSE append error algorithm executes.)
// So we cannot reliably expect the lack or presence of
// 'loadedmetadata' before the MSE append error algortihm executes in
// this case; similarly, mediaElement's resulting readyState may be
// either HAVE_NOTHING or HAVE_METADATA after the append error
// algorithm executes, and the resulting MediaError code would
// respectively be MEDIA_ERR_SRC_NOT_SUPPORTED or MEDIA_ERR_DECODE.
