Steps to reproduce:
- Go to https://de.wikipedia.org/wiki/Notes_by_an_Oxford_Chiel, start editing the page in VE.
- Edit the image (which is a DJVU file with many pages), change something (e.g., add a space to the description).
- Commit the edit to the image.
The image should still show the specified page.
The image shows the first page.
This only affects the view while editing, after saving everything is as expected again.
