Video created for a score with changed title still appears with old title

Steps to replicate:
1. Upload any score to the MuseScore site.
2. Select "Send to YouTube" and create video (as currently the feature to send directly to YouTube is broken).
3. Go back to the score, update the score and change the title.
4. Select again "Send to YouTube" and create another video. The new video still appears with the old title.

To demonstrate, try the above steps with the following score:

The score was originally titled "Old Title", then I changed it to "New Title" before creating a video, but the video still shows "Old Title".
