⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.

Bug description

Everytime I have many photos in a directory, and I scroll down to a certain point and open an image and then close it, the view in the background jumps up and down. Sometimes goes up to the top, and sometimes just scrolls up to a point where my highlighted image section is out of viewpoint.

Same issue has been reported here: viewing photos via nextcloud files. If I scroll down and open and close a photo, it always brings me back to the top.

But as of now I don't see any work-around.
This issue was not present in v27, but it's a regression in v28, most likely when the main view was rewritten in vujes.

Steps to reproduce

Create a folder.
Upload many images, around 100 per se.
Scroll down to a point where you think could be the middle of all images.
Open one image and close it accordingly.
Check if the background view jumps up or down.

Expected behavior

The view should stay in a fixed position when opening any image.
