Bug description

Hi all!

On the web interface, In the files app, in the tags tab, when viewing media by a particular tag, pressing the "next" button on the right of the screen doesn't show the next tagged file in the list, but the next file from whatever folder the tagged file happens to be from.

Steps to reproduce

1. create folder A with three different pictures, let's call them A1, A2, and A3
2. create folder B with three other pictures, let's call them B1, B2, and B3
3. create folder C with three other pictures, let's call them C1, C2, and C3
4. tag A2, B2, and C2 all with the same tag, let's call it T
5. go to the tags tab and select tag T
6. click on image B2 to view it
7. "next" and "previous" buttons (or the arrow keys) will now lead you to B3 and B1 respectively

Expected behavior

The next and previous buttons should lead to C2 and A2, respectively.

No response

Start in the media viewer's next/previous navigation used from the Files app Tags tab, and reproduce the issue with tagged files spread across folders. Trace how the viewer chooses adjacent files; done means the buttons and arrow keys follow the tag result order rather than neighboring files in the current folder.
