- This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).

- Make some modifications, eg, cut, change contrast
- Click Save
- Close
- Open again and observe that there are no changes.
- Click edit and observe that changes have been applied.

Expected behavior
The preview is immediately updated after the changes have been applied after editing.

Research direction
Start by reproducing the image-editing flow in the viewer: open an image in the web UI, edit and save it, close it, then reopen it. Trace the viewer's preview refresh and image-editing entry points to determine why the updated file is not reflected, and verify that reopening shows the saved changes.
