Explain the Problem

While the news app is open, click the nextcloud search bar and type. If you type the letters j or k, the selection on the news reader changes, rather than entering the text into the search bar.
Expected behavior would be that the keyboard shortcuts are only active if there isn't an overlay window or if you are able to type in another area.

Steps to Reproduce
