Bug description

After upgrading Nextcloud to versions higher than 27, users are unable to preview images directly in mobile browsers. Instead, when clicking on an image file, the browser initiates a download of the image file. This behavior contrasts with the expected behavior seen in desktop browsers, where clicking on an image successfully triggers a preview popup. In version 27 of Nextcloud, this functionality worked as expected in both mobile and desktop browsers.

Steps to reproduce

Access Nextcloud instance using a mobile browser (e.g., Chrome on Android/iOS).
Attempt to click on an image file to preview it.
Note that instead of opening a preview popup, the browser initiates a download of the image file.

Expected behavior

Clicking on an image file in both desktop and mobile browsers should trigger a preview popup, allowing users to view the image without downloading it.
