⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. Create a directory with quite a lot of images and videos.
2. Open the directory on mobile.
3. Crash (sometimes).

Expected behaviour

Only thumbnails for what is currently visible should be loaded.

Actual behaviour

Thumbnails for all items are loaded resulting in an out of memory error.

Additional information

1. Maybe a duplicate of OutOfMemoryError - Nextcloud crashes every time "Media" tab is opened #14932. Trace is identical to the one shown there, but this one occurs on the files tab.
2. Reverse Proxy is only in use for external access as I only have one IPv4 address.
