What's not working

Downloading and reading flatpakref files doesn't seem to work.

How to reproduce?

• Goto https://flathub.org/apps/details/org.mozilla.firefox
• Click Install
• The download dialog shows, it likely doesn't have the software app selected (first problem)
• If you still change it to be opened by the software app, it will open the app, but nothing happens (second problem)
