To Reproduce Steps to reproduce the behavior:

1. Create a new deck for testing.
2. Import a long article as an "IR3" note.
3. Open the note and scroll downward.
4. Click "Show Answer".
5. Click "Soon" (or "Later").
6. Close Anki.
7. Reopen Anki and go to the same note.
8. Notice that the position is not restored.
