The above source code pushes the subtitles for the first video, and after that, the track information is modified and reflected in javascript at the [0]th.
The normal operation of the first subtitle has been confirmed. When the second video was played, it was also confirmed that the label was changed normally.
However, there is a problem that the subtitles of the second video are not output normally, and the first subtitles are output.
